Make an appointment with your doctor if you find a lump or other change during a testicular self-exam. Depending on the circumstances, your doctor may do a testicular exam followed by a blood test, ultrasound or biopsy.

Most changes in your testicles aren't caused by testicular cancer. A number of noncancerous conditions can cause changes in your testicles, such as a cyst, injury, infection, hernia and collection of fluid around the testicles (hydrocele).
