There is no way to prevent testicular cancer, but cancers detected early have a high likelihood of being cured.
You should see a doctor if you notice any of the following:
- A painless lump or swelling in a testicle (this is the most common symptom)
- Pain or discomfort in a testicle or in the scrotum
- Any enlargement of a testicle or change in the way it feels
- A feeling of heaviness in the scrotum
- A dull ache in the lower abdomen, back or groin
- A sudden collection of fluid in the scrotum.
Cancer is only one possible cause of these symptoms, and not the most likely one. More often they are caused by injury, infection or something else. But it’s still important to let your doctor know about any changes as soon as possible. Conditions other than cancer can be serious and require treatment.
Some doctors examine the testicles during routine physical exams and advise men to feel their own testicles for any irregularities. The U.S. Preventive Services Task Force, however, advises against routine screening for testicular cancer because there’s no evidence that it’s helpful.
