Testicular self-examination: A monthly procedure for detecting the early signs of testicular cancer. Men should check the testes visually for new swelling or other changes on the skin of the scrotum, roll each testicle between thumb and fingers to detect internal growths, and check the cord (epididymis) on the top and back of each testicle for growths. A warm bath or shower will relax the scrotum, making examination easier. Early detection of testicular cancer greatly improves the likelihood of successful treatment.
