Some men with testicular cancer have no symptoms and the cancer is found during medical tests for other conditions. In about 90 percent of testicular cancer cases, men find a lump on a testicle or notice the testicle is swollen or larger. The lump may or may not cause pain.

Symptoms include:

• A lump in either testicle
• An enlarged testicle
• A feeling of heaviness in the scrotum
• A dull ache in the lower abdomen or groin
• A sudden collection of fluid in the scrotum
• Pain or discomfort in a testicle or in the scrotum
• Enlargement or tenderness of the breasts
