• The tumor is found only in the testicle or in the retroperitoneum (area outside or behind the abdominal wall); and
• The tumor has not spread to organs other than the lungs; and
• The levels of all the tumor markers are slightly above normal.

For seminoma, all of the following must be true:

• The tumor has not spread to organs other than the lungs; and
• The level of alpha-fetoprotein (AFP) is normal. Beta-human chorionic gonadotropin (β-hCG) and lactate dehydrogenase (LDH) may be at any level.

Intermediate Prognosis

For nonseminoma, all of the following must be true:

• The tumor is found in one testicle only or in the retroperitoneum (area outside or behind the abdominal wall); and
• The tumor has not spread to organs other than the lungs; and
• The level of any one of the tumor markers is more than slightly above normal.

For seminoma, all of the following must be true:

• The tumor has spread to organs other than the lungs; and
• The level of AFP is normal. β-hCG and LDH may be at any level.

Poor Prognosis

For nonseminoma, at least one of the following must be true:

• The tumor is in the center of the chest between the lungs; or
• The tumor has spread to organs other than the lungs; or
• The level of any one of the tumor markers is high.

There is no poor prognosis grouping for seminoma testicular tumors.

A link to a list of current clinical trials is included for each treatment section. For some types or stages of cancer, there may not be any trials listed. Check with your doctor for clinical trials that are not listed here but may be right for you.

Stage I Testicular Cancer

Treatment of stage I testicular cancer depends on whether the cancer is a seminoma or a nonseminoma.

Treatment of seminoma may include the following:

• Surgery to remove the testicle, with or without radiation therapy to lymph nodes in the abdomen after the surgery, with lifelong follow-up.
• Surgery to remove the testicle, followed by chemotherapy and lifelong follow-up.

Treatment of nonseminoma may include the following:

• Surgery to remove the testicle and lymph nodes in the abdomen, with lifelong follow-up.
• Surgery to remove the testicle, with lifelong follow-up.
• Surgery followed by chemotherapy for patients at high risk of recurrence, with lifelong follow-up.

Check for U.S. clinical trials from NCI’s PDQ Cancer Clinical Trials Registry that are now accepting patients with stage I malignant testicular germ cell tumor. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. General information about clinical trials is available from the NCI Web site.

Stage II Testicular Cancer

Treatment of stage II testicular cancer depends on whether the cancer is a seminoma or a nonseminoma.

Treatment of seminoma may include the following:

• When the tumor is 5 centimeters or smaller, treatment is usually surgery to remove the testicle followed by radiation therapy to lymph nodes in the abdomen and pelvis, with lifelong follow-up.
• When the tumor is larger than 5 centimeters, treatment is usually surgery to remove the testicle followed by combination chemotherapy or radiation therapy to lymph nodes in the abdomen and pelvis, with lifelong follow-up.

Treatment of nonseminoma may include the following:

• Surgery to remove the testicle and lymph nodes, with lifelong follow-up.
• Surgery to remove the testicle and lymph nodes, followed by combination chemotherapy and lifelong follow-up.
• Surgery to remove the testicle followed by combination chemotherapy and a second surgery if cancer remains, with lifelong follow-up.
• Combination chemotherapy before surgery to remove the testicle, for cancer that has spread and is thought to be life-threatening.
• A clinical trial of combination chemotherapy instead of removing the lymph nodes.

Check for U.S. clinical trials from NCI’s PDQ Cancer Clinical Trials Registry that are now accepting patients with stage II malignant testicular germ cell tumor. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. General information about clinical trials is available from the NCI Web site.

Stage III Testicular Cancer

Treatment of stage III testicular cancer depends on whether the cancer is a seminoma or a nonseminoma.

Treatment of seminoma may include the following:

• Surgery to remove the testicle followed by combination chemotherapy. Any tumor remaining after treatment will need lifelong follow-up.

General information about clinical trials is available from the NCI Web site.

Treatment Options for Recurrent Testicular Cancer

Treatment of recurrent testicular cancer may include the following:

• Combination chemotherapy.
• High-dose chemotherapy with bone marrow transplant.
• Surgery to remove cancer that has either:
  • come back more than 2 years after complete remission; or
  • come back in only one place and does not respond to chemotherapy.
• A clinical trial of a new therapy.

1. What is testicular cancer?

Testicular cancer is a disease in which cells become malignant (cancerous) in one or both testicles.

The testicles (also called testes or gonads) are a pair of male sex glands. They produce and store sperm and are the main source of testosterone (male hormones) in men. These hormones control the development of the reproductive organs and other male physical characteristics. The testicles are located under the penis in a sac-like pouch called the scrotum.

Based on the characteristics of the cells in the tumor, testicular cancers are classified as seminomas or nonseminomas. Other types of cancer that arise in the testicles are rare and are not described here. Seminomas may be one of three types: classic, anaplastic, or spermatocytic. Types of nonseminomas include choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumors. Testicular tumors may contain both seminoma and nonseminoma cells.

Testicular cancer accounts for only 1 percent of all cancers in men in the United States. About 8,000 men are diagnosed with testicular cancer, and about 390 men die of this disease each year (1). Testicular cancer occurs most often in men between the ages of 20 and 39, and is the most common form of cancer in men between the ages of 15 and 34. It is most common in white men, especially those of Scandinavian descent. The testicular cancer rate has more than doubled among white men in the past 40 years, but has only recently begun to increase among black men. The reason for the racial differences in incidence is not known.

2. What are the risk factors for testicular cancer?
   • Undescended testicle (cryptorchidism): Normally, the testicles descend from inside the abdomen into the scrotum before birth. The risk of testicular cancer is increased in males with a testicle that does not move down into the scrotum. This risk does not change even after surgery to move the testicle into the scrotum. The increased risk applies to both testicles.
   • Congenital abnormalities: Men born with abnormalities of the testicles, penis, or kidneys, as well as those with inguinal hernia (hernia in the groin area, where the thigh meets the abdomen), may be at increased risk.
   • History of testicular cancer: Men who have had testicular cancer are at increased risk of developing cancer in the other testicle.
   • Family history of testicular cancer: The risk for testicular cancer is greater in men whose brother or father has had the disease.

The exact causes of testicular cancer are not known. However, studies have shown that several factors increase a man’s chance of developing this disease.

3. How is testicular cancer detected? What are symptoms of testicular cancer?
   • a painless lump or swelling in a testicle
   • pain or discomfort in a testicle or in the scrotum
   • any enlargement of a testicle or change in the way it feels
   • a feeling of heaviness in the scrotum
   • a dull ache in the lower abdomen, back, or groin
   • a sudden collection of fluid in the scrotum

Most testicular cancers are found by men themselves. Also, doctors generally examine the testicles during routine physical exams. Between regular checkups, if a man notices anything unusual about his testicles, he should talk with his doctor. Men should see a doctor if they notice any of the following symptoms:

These symptoms can be caused by cancer or by other conditions. It is important to see a doctor to determine the cause of any of these symptoms.

4. How is testicular cancer diagnosed?
   • Blood tests that measure the levels of tumor markers. Tumor markers are substances often found in higher-than-normal amounts when cancer is present. Tumor markers such as alpha-fetoprotein (AFP), Beta-human chorionic gonadotropin (ßHCG), and lactate dehydrogenase (LDH) may suggest the presence of a testicular tumor, even if it is too small to be detected by physical exams or imaging tests.
   • Ultrasound, a test in which high-frequency sound waves are bounced off internal organs and tissues. Their echoes produce a picture called a sonogram. Ultrasound of the scrotum can show the presence and size of a mass in the testicle. It is also helpful in ruling out other conditions, such as swelling due to infection or a collection of fluid unrelated to cancer.
   • Biopsy (microscopic examination of testicular tissue by a pathologist) to determine whether cancer is present. In nearly all cases of suspected cancer, the entire affected testicle is removed through an incision in the groin. This procedure is called radical inguinal orchiectomy. In rare cases (for example, when a man has only one testicle), the surgeon performs an inguinal biopsy, removing a sample of tissue from the testicle through an incision in the groin and proceeding with orchiectomy only if the pathologist finds cancer cells. (The surgeon does not cut through the scrotum to remove tissue. If the problem is cancer, this procedure could cause the disease to spread.)

To help find the cause of symptoms, the doctor evaluates a man’s general health. The doctor also performs a physical exam and may order laboratory and diagnostic tests. These tests include:

If testicular cancer is found, more tests are needed to find out if the cancer has spread from the testicle to other parts of the body. Determining the stage (extent) of the disease helps the doctor to plan appropriate treatment.

5. How is testicular cancer treated? What are the side effects of treatment?
   • Surgery to remove the testicle through an incision in the groin is called a radical inguinal orchiectomy. Men may be concerned that losing a testicle will affect their ability to have sexual intercourse or make them sterile (unable to produce children). However, a man with one healthy testicle can still have a normal erection and produce sperm. Therefore, an operation to remove one testicle does not make a man impotent (unable to have an erection) and seldom interferes with fertility (the ability to produce children). For cosmetic purposes, men can have a prosthesis (an artificial testicle) placed in the scrotum at the time of their orchiectomy or at any time afterward.

   Some of the lymph nodes located deep in the abdomen may also be removed (lymph node dissection). This type of surgery does not usually change a man’s ability to have an erection or an orgasm, but it can cause problems with fertility if it interferes with ejaculation. Patients may wish to talk with their doctor about the possibility of removing the lymph nodes using a special nerve-sparing surgical technique that may preserve the ability to ejaculate normally.

   • Radiation therapy (also called radiotherapy) uses high-energy rays to kill cancer cells and shrink tumors. It is a local therapy, meaning that it affects cancer cells only in the treated areas. External radiation (from a machine outside the body), aimed at the lymph nodes in the abdomen, is used to treat seminomas. It is usually given after surgery. Because nonseminomas are less sensitive to radiation, men with this type of cancer usually do not undergo radiation therapy.

   Radiation therapy affects normal as well as cancerous cells. The side effects of radiation therapy depend mainly on the treatment dose. Common side effects include fatigue, skin changes at the site where the treatment is given, loss of appetite, nausea, and diarrhea. Radiation therapy interferes with sperm production, but many patients regain their fertility over a period of 1 to 2 years.

   • Chemotherapy is the use of anticancer drugs to kill cancer cells. When chemotherapy is given to testicular cancer patients, it is usually given as adjuvant therapy (after surgery) to destroy cancerous cells that may remain in the body. Chemotherapy may also be the initial treatment if the cancer is advanced; that is, if it has spread outside the testicle at the time of the diagnosis. Most anticancer drugs are given by injection into a vein.

   Chemotherapy is a systemic therapy, meaning drugs travel through the bloodstream and affect normal as well as cancerous cells throughout the body. The side effects depend largely on the specific drugs and the doses. Common side effects include nausea, hair loss, fatigue, diarrhea, vomiting, fever, chills, coughing/shortness of breath, mouth sores, or skin rash. Other side effects include dizziness, numbness, loss of reflexes, or difficulty hearing. Some anticancer drugs also interfere with sperm production. Although the reduction in sperm count is permanent for some patients, many others recover their fertility.

   Some men with advanced or recurrent testicular cancer may undergo treatment with very high doses of chemotherapy. These high doses of chemotherapy kill cancer cells, but they also destroy the bone marrow, which makes and stores blood cells. Such treatment can be given only if patients undergo a bone marrow transplant. In a transplant, bone marrow stem cells are removed from the patient before chemotherapy is administered. These cells are frozen temporarily and then thawed and returned to the patient through a needle (like a blood transfusion) after the high-dose chemotherapy has been administered.

Although the incidence of testicular cancer has risen in recent years, more than 95 percent of cases can be cured. Treatment is more likely to be successful when testicular cancer is found early. In addition, treatment can often be less aggressive and may cause fewer side effects.

Most men with testicular cancer can be cured with surgery, radiation therapy, and/or chemotherapy. The side effects depend on the type of treatment and may be different for each person.

Seminomas and nonseminomas grow and spread differently and are treated differently. Nonseminomas tend to grow and spread more quickly; seminomas are more sensitive to radiation. If the tumor contains both seminoma and nonseminoma cells, it is treated as a nonseminoma. Treatment also depends on the stage of the cancer, the patient’s age and general health, and other factors. Treatment is often provided by a team of specialists, which may include a surgeon, a medical oncologist, and a radiation oncologist.

The three types of standard treatment are described below.

Men with testicular cancer should discuss their concerns about sexual function and fertility with their doctor. It is important to know that men with testicular cancer often have fertility problems even before their cancer is treated. If a man has pre-existing fertility problems, or if he is to have treatment that might lead to infertility, he may want to ask the doctor about sperm banking (freezing sperm before treatment for use in the future). This procedure allows some men to have children even if the treatment causes loss of fertility.

6. Is follow-up treatment necessary? What does it involve?

Regular follow-up exams are extremely important for men who have been treated for testicular cancer. Like all cancers, testicular cancer can recur (come back). Men who have had testicular cancer should see their doctor regularly and should report any unusual symptoms right away. Follow-up varies for different types and stages of testicular cancer. Generally, patients are checked frequently by their doctor and have regular blood tests to measure tumor marker levels. They also have regular x-rays and computed tomography, also called CT scans or CAT scans (detailed pictures of areas inside the body created by a computer linked to an x-ray machine). Men who have had testicular cancer have an increased likelihood of developing cancer in the remaining testicle. Patients treated with chemotherapy may have an increased risk of certain types of leukemia, as well as other types of cancer. Regular follow-up care ensures that changes in health are discussed and that problems are treated as soon as possible.

7. Are clinical trials (research studies) available for men with testicular cancer?

Yes. Participation in clinical trials is an important treatment option for many men with testicular cancer. To develop new treatments, and better ways to use current treatments, the National Cancer Institute (NCI) is sponsoring clinical trials (research studies with people) in many hospitals and cancer centers around the country. Clinical trials are a critical step in the development of new methods of treatment. Before any new treatment can be recommended for general use, doctors conduct clinical trials to find out whether the treatment is safe for patients and effective against the disease.

The testicles are 2 egg-shaped glands located inside the scrotum (a sac of loose skin that lies directly below the penis). The testicles are held within the scrotum by the spermatic cord, which also contains the vas deferens and vessels and nerves of the testicles.

testicular cancer

Anatomy of the male reproductive and urinary systems, showing the testicles, prostate, bladder, and other organs.

The testicles are the male sex glands and produce testosterone and sperm. Germ cells within the testicles produce immature sperm that travel through a network of tubules (tiny tubes) and larger tubes into the epididymis (a long coiled tube next to the testicles) where the sperm mature and are stored.

Almost all testicular cancers start in the germ cells. The two main types of testicular germ cell tumors are seminomas and nonseminomas. These 2 types grow and spread differently and are treated differently. Nonseminomas tend to grow and spread more quickly than seminomas. Seminomas are more sensitive to radiation. A testicular tumor that contains both seminoma and nonseminoma cells is treated as a nonseminoma.

Testicular cancer is the most common cancer in men 20 to 35 years old.

Health history can affect the risk of developing testicular cancer.

Anything that increases the chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor. Risk factors for testicular cancer include:

• Having had an undescended testicle.
• Having had abnormal development of the testicles.
• Having a personal or family history of testicular cancer.
• Being white.

Possible signs of testicular cancer include swelling or discomfort in the scrotum.

These and other symptoms may be caused by testicular cancer. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:

• A painless lump or swelling in either testicle.
• A change in how the testicle feels.
• A dull ache in the lower abdomen or the groin.
• A sudden build-up of fluid in the scrotum.
• Pain or discomfort in a testicle or in the scrotum.

Tests that examine the testicles and blood are used to detect (find) and diagnose testicular cancer.

The following tests and procedures may be used:

• Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. The testicles will be examined to check for lumps, swelling, or pain. A history of the patient’s health habits and past illnesses and treatments will also be taken.
• Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram.
• Serum tumor marker test: A procedure in which a sample of blood is examined to measure the amounts of certain substances released into the blood by organs, tissues, or tumor cells in the body. Certain substances are linked to specific types of cancer when found in increased levels in the blood. These are called tumor markers. The following 3 tumor markers are used to detect testicular cancer:
  • Alpha-fetoprotein (AFP).
  • Beta-human chorionic gonadotropin (β-hCG).
  • Lactate dehydrogenase (LDH).

  Tumor marker levels are measured before radical inguinal orchiectomy and biopsy, to help diagnose testicular cancer.

• Radical inguinal orchiectomy and biopsy: A procedure to remove the entire testicle through an incision in the groin. A tissue sample from the testicle is then viewed under a microscope to check for cancer cells. (The surgeon does not cut through the scrotum into the testicle to remove a sample of tissue for biopsy, because if cancer is present, this procedure could cause it to spread into the scrotum and lymph nodes.) If cancer is found, the cell type (seminoma or nonseminoma) is determined in order to help plan treatment.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) and treatment options depend on the following:

• Stage of the cancer (whether it is in or near the testicle or has spread to other places in the body, and blood levels of AFP, β-hCG, and LDH).
• Type of cancer.
• Size of the tumor.
• Number and size of retroperitoneal lymph nodes.

Testicular cancer is often curable.

Treatment for testicular cancer can cause infertility.

Certain treatments for testicular cancer can cause infertility that may be permanent. Patients who may wish to have children should consider sperm banking before having treatment. Sperm banking is the process of freezing sperm and storing it for later use.

Surgery

Surgery to remove the testicle (radical inguinal orchiectomy) and some of the lymph nodes may be done at diagnosis and staging. (See the General Information and Stages sections of this summary.) Tumors that have spread to other places in the body may be partly or entirely removed by surgery.

Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to increase the chances of a cure, is called adjuvant therapy.

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.

New types of treatment are being tested in clinical trials.

This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.

High-dose chemotherapy with stem cell transplant

High-dose chemotherapy with stem cell transplant is a method of giving high doses of chemotherapy and replacing blood-forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body’s blood cells.

Patients may want to think about taking part in a clinical trial.

For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.

Many of today’s standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.

Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.

Patients can enter clinical trials before, during, or after starting their cancer treatment.

Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.

Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI’s clinical trials database.

Follow-up tests may be needed.

Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.

Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

Men who have had testicular cancer have an increased risk of developing cancer in the other testicle. A patient is advised to regularly check the other testicle and report any unusual symptoms to a doctor right away.

Lifelong clinical exams are very important. The patient will probably have check-ups once per month during the first year after surgery, every other month during the next year, and less often after that.

The process used to find out if cancer has spread within the testicles or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process:

• Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
• CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
• Lymphangiography: A procedure used to x-ray the lymph system. A dye is injected into the lymph vessels in the feet. The dye travels upward through the lymph nodes and lymph vessels, and x-rays are taken to see if there are any blockages. This test helps find out whether cancer has spread to the lymph nodes.
• Abdominal lymph node dissection: A procedure to examine lymph nodes in the abdomen. Lymph nodes are removed and a pathologist checks them for cancer cells. For patients with nonseminoma, removing the lymph nodes may help stop the spread of disease. Cancer cells in the lymph nodes of seminoma patients can be treated with radiation therapy.
• Radical inguinal orchiectomy and biopsy: A procedure to remove the entire testicle through an incision in the groin. A tissue sample from the testicle is then viewed under a microscope to check for cancer cells. (The surgeon does not cut through the scrotum into the testicle to remove a sample of tissue for biopsy, because if cancer is present, this procedure could cause it to spread into the scrotum and lymph nodes.)
• Serum tumor marker test: A procedure in which a sample of blood is examined to measure the amounts of certain substances released into the blood by organs, tissues, or tumor cells in the body. Certain substances are linked to specific types or cancer when found in increased levels in the blood. These are called tumor markers. The following 3 tumor markers are used in staging testicular cancer:
  • Alpha-fetoprotein (AFP)
  • Beta-human chorionic gonadotropin (β-hCG).
  • Lactate dehydrogenase (LDH).

  Tumor marker levels are measured again, after radical inguinal orchiectomy and biopsy, in order to determine the stage of the cancer. This helps to show if all of the cancer has been removed or if more treatment is needed. Tumor marker levels are also measured during follow-up as a way of checking if the cancer has come back.

There are three ways that cancer spreads in the body.

The three ways that cancer spreads in the body are:

• Through tissue. Cancer invades the surrounding normal tissue.
• Through the lymph system. Cancer invades the lymph system and travels through the lymph vessels to other places in the body.
• Through the blood. Cancer invades the veins and capillaries and travels through the blood to other places in the body.

When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.

The following stages are used for testicular cancer:Stage 0 (Carcinoma in Situ)

In stage 0, abnormal cells are found in the tiny tubules where the sperm cells begin to develop. These abnormal cells may become cancer and spread into nearby normal tissue. All tumor marker levels are normal. Stage 0 is also called carcinoma in situ.

Stage I

In stage I, cancer has formed. Stage I is divided into stage IA, stage IB, and stage IS and is determined after a radical inguinal orchiectomy is done.

• In stage IA, cancer is in the testicle and epididymis and may have spread to the inner layer of the membrane surrounding the testicle. All tumor marker levels are normal.
• In stage IB, cancer:
  • is in the testicle and the epididymis and has spread to the blood or lymph vessels in the testicle; or
  • has spread to the outer layer of the membrane surrounding the testicle; or
  • is in the spermatic cord or the scrotum and may be in the blood or lymph vessels of the testicle.

  All tumor marker levels are normal.

• In stage IS, cancer is found anywhere within the testicle, spermatic cord, or the scrotum and either:
  • all tumor marker levels are slightly above normal; or
  • one or more tumor marker levels are moderately above normal or high.

Pea, peanut, walnut, and lime show tumor sizes.

Stage II

Stage II is divided into stage IIA, stage IIB, and stage IIC and is determined after a radical inguinal orchiectomy is done.

• In stage IIA, cancer:
  • is anywhere within the testicle, spermatic cord, or scrotum; and
  • has spread to up to 5 lymph nodes in the abdomen, none larger than 2 centimeters.

  All tumor marker levels are normal or slightly above normal.

• In stage IIB, cancer is anywhere within the testicle, spermatic cord, or scrotum; and either:
  • has spread to up to 5 lymph nodes in the abdomen; at least one of the lymph nodes is larger than 2 centimeters, but none are larger than 5 centimeters; or
  • has spread to more than 5 lymph nodes; the lymph nodes are not larger than 5 centimeters.

  All tumor markers levels are normal or slightly above normal.

• In stage IIC, cancer:
  • is anywhere within the testicle, spermatic cord, or scrotum; and
  • has spread to a lymph node in the abdomen that is larger than 5 centimeters.

  All tumor marker levels are normal or slightly above normal.

Stage III

Stage III is divided into stage IIIA, stage IIIB, and stage IIIC and is determined after a radical inguinal orchiectomy is done.

• In stage IIIA, cancer:
  • is anywhere within the testicle, spermatic cord, or scrotum; and
  • may have spread to one or more lymph nodes in the abdomen; and
  • has spread to distant lymph nodes or to the lungs.

  The level of one or more tumor markers may range from normal to slightly above normal.

• In stage IIIB, cancer:
  • is anywhere within the testicle, spermatic cord, or scrotum; and
  • may have spread to one or more nearby or distant lymph nodes or to the lungs.

  The level of one or more tumor markers may range from normal to high.

• In stage IIIC, cancer:
  • is anywhere within the testicle, spermatic cord, or scrotum; and
  • may have spread to one or more nearby or distant lymph nodes or to the lungs or anywhere else in the body.

  The level of one or more tumor markers may range from normal to very high.
