Most testicular cancers can be found at an early stage. Ninety percent of men diagnosed with the disease have a lump on a testicle or notice that the testicle is swollen. While the lump is often painless, it can be uncomfortable. Some men with testicular cancer feel heaviness or aching in their lower belly or scrotum. Less common symptoms include breast growth or tenderness, loss of sex drive, and growth of hair on face and body before puberty.
If you have any of these signs or symptoms, speak with your doctor right away. While testicular cancer is sometimes found during testing for other problems, such as fertility tests, a testicular exam should be part of your routine physical exam.
