How do I check my balls for lumps?

It's pretty easy. It's best to examine your testicles after a warm bath or shower.

• Support your balls in the palm of one hand. Note the size and weight of your testicles. This will help you to detect any changes in the future.  
• Find the epididymis, the tube that carries sperm to the penis. This can be felt at the top and back of each testicle. This is one lump that is supposed to be there.
• Now examine each testicle in more detail by rolling it between your fingers and thumb. Press firmly but gently to feel for any lumps, swellings or changes in firmness.

Examine yourself every couple of months or when you feel like it. Testicular cancer is very uncommon so don't get obsessed with it. But if you do find anything unusual, don't wait for it to disappear or start throbbing - see your doctor.
