When abnormal cells in the body grow out of control, it is called cancer. A growth of cancer cells is called a tumor. If the cancer cells break away from the tumor and spread to other parts of the body, the tumor is called metastatic.
Testicular cancer is uncontrolled growth of abnormal cells in one or both testicles. The testicles are part of the male reproductive system. They are in a sac of loose skin, called the scrotum or scrotal sac, which lies directly below the base of the penis. With time, the growth of the cancer causes the testicle to enlarge or form a lump that can be seen or felt. The lump may not cause any discomfort or it may be painful.
In metastatic testicular cancer the cancer has spread to other parts of the body, starting new tumors. The most common places for the new tumors (metastases) are the lungs, lymph nodes, lungs, and later the liver.
The cause of testicular cancer is not known, but there are several risk factors. For example, men who have or have had an undescended testicle, whether or not it was surgically corrected, have a higher risk of developing testicular cancer. Testicular cancer is most common in men aged 20 to 39. It is rare after the age of 40.
Sometimes the first symptoms of testicular cancer are caused by metastases before the original tumor in the testicle is noticed. The new tumors may cause symptoms because they affect the function of the organs in which they are growing.
The symptoms of metastases depend on where the tumors are. If a new tumor has grown into the abdominal lymph nodes and lungs, for example, possible symptoms are:
A physical exam, chest X-ray, or CT scan may show that a tumor is growing in another part of the body (for example, the lungs). You may have blood tests to look for alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (beta-hCG). These substances are made normally by the body in small amounts, but often by testicular cancers in large amounts. The amounts of these substances in the blood may relate to the amount of cancer in your body. However, AFP and beta-hCG are not damaging or dangerous.
The treatment for this cancer depends on how large the tumor is, what cell type the tumor is, where it has spread, and your physical condition. Possible treatments are:
After treatment your healthcare provider will recommend regular checkups for the first year. Then you will need checkups slightly less often for the next 2 years to see if the cancer recurs. It is important to follow your provider's recommendations so that any recurrence can be detected early. Most recurrences happen within the first 2 years after treatment.
If your treatment destroys the cancer, the symptoms caused by the cancer will go away. The treatment may cause some discomfort or side effects, but these usually improve after treatment is done.
How long you will live after metastatic testicular cancer is discovered depends on how large the tumor is in the testicle, how much the cancer has spread, where it has spread, and your physical condition. The chances of a complete recovery are usually very good and much better than they are for many other cancers. Cure rates for men with metastatic testicular cancer are 80 to 90%.

Because the chance for cure depends on finding the cancer early and treating it before it spreads too far, it is important to examine your testicles often. Support your testicles with one hand and feel each one with your other hand. You will feel the smooth bump or epididymis, which covers the top, back, and bottom of each testicle. Gently separate it from the testicle with your finger and feel the testicle itself. Report any lump in the scrotum or testicle, pain or discomfort, or enlargement of the scrotum to a healthcare provider as soon as possible.
Regular checkups are especially important if you have had an undescended testicle.
