Testicular Cancer commonly affects men in the 20-35 year old age range.
It can affect older men as well. Each year just under 2,000 men are diagnosed with this and 70 men die.
If you take note of any changes to the testicles, any lumps, or pain in the groin and go to your doctor, it is one of the most treatable forms of cancer and 95% of men will make a full recovery.
