Testicular cancer is not common. It is often first discovered by the man himself, or his sex partner, as a lump or an enlarged and swollen testicle. In the early stages of testicular cancer, the lump, which may be about the size of a pea, usually is not painful. Testicular cancer has a high cure rate.
Testicular self-examination (TSE) may detect testicular cancer at an early stage. Many doctors do not believe that monthly TSE is needed for men who are at average risk for testicular cancer. Monthly TSE may be recommended for men who are at high risk for testicular cancer. This includes men with a history of an undescended testicle or a family or personal history of testicular cancer.
