Check your testicles every month by gently rolling them, one at a time, between your thumb and fingers to feel for any unusual lumps or bumps. You’ll feel a hard ridge on the upper back of each ball. This is the epididymis, where sperm is stored, and it’s normal to feel it here.
If you feel any lumps, it probably isn’t cancer, but get it checked by a doctor. Other warning signs include:
- one ball growing larger or heavier than the other
- an ache in your balls
- bleeding from your penis.
If you notice any of these, see your doctor. If caught early, testicular cancer can usually be treated successfully.
