Im 24. I have little swelling ( May be a lump too..Im not sure) on the left side of testis. I masturbate and last weeks I had a over masturbation ( Almost daily). Ive stopped and controlled it now. I dont know what this is swelling....it has a little pain. Does this lead to Cancer?
Over or under masturbation doesn't lead to cancer. It may lead to infection of testis called orchids. Please consult your surgeon or get USG abdomen done.
