A male should perform a self-testicular exam once a month to check for any lumps or abnormalities that could indicate testicular cancer.
Step-by-step explanation:
A male should perform a self-testicular exam once a month. This is done to check for any lumps or abnormalities in the testes that could be a sign of testicular cancer. The exam can be done in the privacy of your own home using your hands, feeling for any changes or irregularities in the shape or size of the testes. It is important to perform the exam in a relaxed state, such as during or after a warm shower, when the scrotal skin is relaxed.
