Bumps and Lumps
There are many different causes of bumps on a man's balls and most are harmless. Some of the more common causes include varicocele and epididymal cysts. A varicocele is an enlarged vein, like a varicose vein. These can affect fertility and cause pain but can also be harmless. Epididymal cysts are fluid-filled lumps located at the back of the testicles. These usually don't require treatment. Only four out of every 100 lumps found on men's balls are cancer but they are still something to bring up to your doctor. "I say that if they feel anything that's funny or different, it's definitely worth getting checked out," says Smith.
