Overview

Testicular cancer is not common. It is often first discovered by the person or a 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.

The Canadian Cancer Society (CCS) recommends that all men should know how their testicles normally look and feel and that men should talk to their doctor if they notice any changes in their testicles.^{footnote 1}

Monthly testicular self-examinations may be recommended for those who are at high risk for testicular cancer. This includes anyone who has a history of an undescended testicle or a family or personal history of testicular cancer.
