The situation when one or both of the testicles turn malignant is referred to as testicular cancer. The exact cause of the disease is not known but the risk factors include undescended testicles, congenital abnormalities and history of testicular cancer in family which is most common among the males of age 20-35 year.

The symptoms to look out for in the case of testicular cancer are testicular pain or discomfort, testicular enlargement, abdomen pain or collection of fluid in the scrotum. Testicular cancer can be cured either by surgery, radiation therapy or chemotherapy but the treatment affects the fertility and the sexual functions.
