This information is produced and provided by the National Cancer Institute (NCI). The information in this topic may have changed since it was written. For the most current information, contact the National Cancer Institute via the Internet web site at http://cancer.gov or call 1-800-4-CANCER.
Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage. When abnormal tissue or cancer is found early, it may be easier to treat. By the time symptoms appear, cancer may have begun to spread.
Scientists are trying to better understand which people are more likely to get certain types of cancer. They also study the things we do and the things around us to see if they cause cancer. This information helps doctors recommend who should be screened for cancer, which screening tests should be used, and how often the tests should be done.
It is important to remember that your doctor does not necessarily think you have cancer if he or she suggests a screening test. Screening tests are given when you have no cancer symptoms.
If a screening test result is abnormal, you may need to have more tests done to find out if you have cancer. These are called diagnostic tests.
Testicular cancer is a disease in which malignant (cancer) cells form in the tissues of one or both testicles.
The testicles are 2 egg-shaped glands 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. The spermatic cord also contains the vas deferens and vessels and nerves of the testicles.Anatomy of the male reproductive and urinary systems, showing the testicles, prostate, bladder, and other organs.
The testicles are the male sex glands and make testosterone and sperm. Germ cells in the testicles make immature sperm. These sperm travel through a network of tubules (tiny tubes) and larger tubes into the epididymis (a long coiled tube next to the testicles). This is 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.
See the PDQ summary on Testicular Cancer Treatment for more information about testicular cancer.
Testicular cancer is the most common cancer in men aged 15 to 34 years.
Testicular cancer is very rare, but it is the most common cancer found in men between the ages of 15 and 34. White men are four times more likely than black men to have testicular cancer
Testicular cancer can usually be cured.
Although the number of new cases of testicular cancer has doubled in the last 40 years, the number of deaths caused by testicular cancer has decreased greatly because of better treatments. Testicular cancer can usually be cured, even in late stages of the disease. (See the PDQ summary on Testicular Cancer Treatment for more information.)
A condition called cryptorchidism (an undescended testicle) is a risk factor for 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. Talk to your doctor if you think you may be at risk. Risk factors for testicular cancer include the following:
Men who have cryptorchidism, a testicle that is not normal, or testicular carcinoma in situ have an increased risk of testicular cancer in one or both testicles, and need to be followed closely.
Tests are used to screen for different types of cancer.
Some screening tests are used because they have been shown to be helpful both in finding cancers early and in decreasing the chance of dying from these cancers. Other tests are used because they have been shown to find cancer in some people; however, it has not been proven in clinical trials that use of these tests will decrease the risk of dying from cancer.
Scientists study screening tests to find those with the fewest risks and most benefits. Cancer screening trials also are meant to show whether early detection (finding cancer before it causes symptoms) decreases a person's chance of dying from the disease. For some types of cancer, the chance of recovery is better if the disease is found and treated at an early stage.
Information about ongoing clinical trials is available from the NCI Web site.
There is no standard or routine screening test for testicular cancer.
There is no standard or routine screening test used for early detection of testicular cancer. Most often, testicular cancer is first found by men themselves, either by chance or during self-exam. Sometimes the cancer is found by a doctor during a routine physical exam.
No studies have been done to find out if testicular self-exams, regular exams by a doctor, or other screening tests in men with no symptoms would decrease the risk of dying from this disease. However, routine screening probably would not decrease the risk of dying from testicular cancer. This is partly because testicular cancer can usually be cured at any stage. Finding testicular cancer early may make it easier to treat. Patients who are diagnosed with testicular cancer that has not spread to other parts of the body may need less chemotherapy and surgery, resulting in fewer side effects.
If a lump is found in the testicle by the patient or during a routine physical exam, tests may be done to check for cancer. Some tests have risks, and may cause anxiety.
The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.
Editorial changes were made to this summary.
Physician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.
PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government's center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.
Purpose of This Summary
This PDQ cancer information summary has current information about testicular cancer screening. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.
Reviewers and Updates
Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Date Last Modified") is the date of the most recent change.
The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Screening and Prevention Editorial Board.
Clinical Trial Information
A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Clinical trials are listed in PDQ and can be found online at NCI's Web site. Many cancer doctors who take part in clinical trials are also listed in PDQ. For more information, call the Cancer Information Service 1-800-4-CANCER (1-800-422-6237).
