By Mayo Clinic staffA testicular exam doesn't pose any risks. If you notice a cause for concern, however, the follow-up exam might lead to unnecessary worry and medical attention. For example, if you discover a suspicious lump, you may end up having a procedure to remove tissue for examination (biopsy). If it turns out the lump was noncancerous (benign), you might feel that you've undergone an invasive procedure unnecessarily.
Testicular self-exams alone don't reduce the number of deaths from testicular cancer. Because of the low incidence of testicular cancer and the potential for unnecessary anxiety and intervention, some men choose not to do routine testicular exams.
