Testicular Cancer Risk Factors and Symptoms

Testicular cancer mainly affects men between the ages of 20 and 34. Factors that may increase a man's risk of developing testicular cancer are:

• Abnormal testicle development
• History of an undescended testicle
• A family history of the cancer

Symptoms include pain, swelling, or lumps in your testicles or groin area.  If you experience any of these symptoms you should contact your doctor.
