Is a lump in the testicle always cancer?

Not all lumps in the testicle are cancer. Some lumps can be caused by benign conditions, such as an inflammation of the testicle or a cyst. However, because testicular cancer is relatively common in men between the ages of 15 and 45, it's important to have any lump in the testicle evaluated by a doctor as soon as possible. Early diagnosis and treatment of testicular cancer can improve the chances of a successful outcome.
