Testicular cancer is a growth of cancer cells in one or both testicles. The testicles are a pair of male sex glands. They make and store sperm and male hormones. Types of testicular cancer include:
Cancer occurs when cells in the body divide without control or order. They grow to form a tumor. These growths can invade nearby tissue and can later spread to other areas of the body.
It is not clear what the exact cause is. Genetics and environment may both play a role.
Testicular cancer is more common in men age 25 to 35 years. Other things that may increase your chance of testicular cancer are:
Testicular cancer may cause:
Early diagnosis will improve outcomes. Your doctor may do testicular exams at check ups. They may also talk about self examinations to look for any changes. Changes should be checked out by a doctor.
The doctor will ask about your symptoms and past health. A physical exam will be done. Your doctor may order:
More tests may be done once cancer is found:
The tests will help to find the type and stage of cancer. Staging is used to guide a treatment plan. Testicular cancer is stage 1 to 3. Stage 1 cancer is only in local tissue. Stage III cancer has spread to other parts of the body.
Cancer treatment will be based on the stage and type of cancer. The plan will often have more than 1 type of therapy. Steps may include:
The goal is to remove as much cancer as possible. Some local healthy tissue may also be removed. Lymph nodes in the area may also need to be removed. They may be tested for cancer. More nodes may be removed if cancer is found in the nodes.
Radiation therapy will kill cancer cells and shrink tumors. It may be used on the area after surgery. It can help to kill any cancer cells that could not be seen. It may also be used to treat tumors that are causing problems but cannot be removed with surgery.
Chemotherapy is the use of drugs to kill cancer cells. It may be given as pills, injections, or by IV. The drugs travel through the body. It targets cancer cells, but some healthy cells can be damaged as well. It may be used along with radiation therapy for some types of testicular cancers. It may also be used for cancer that has spread.
Treatment can cause fertility problems. Sperm banking and other treatments may help.
There are no steps for testicular prevention in most.
