A Look at the Warning Signs of Testicular Cancer

When diagnosed in early stages, testicular cancer is very treatable through robotic surgery, chemotherapy, and radiation. Being vigilant to the warning signs is a crucial part of an early diagnosis, so it is important for men to educate themselves about the potential symptoms. If you experience any of these signs, consider seeing your doctor for further evaluation.

Lump or Swelling

A lump or swelling in one testicle is the most common sign of testicular cancer. The lump is typically painless and may be as small as a pea, but can grow in size as the cancer progresses. Swelling may be accompanied by a feeling of heaviness or a change in the feeling of the scrotum. For example, you may notice tightness or firmness that wasn’t there previously. This symptom may be accompanied by fluid accumulation in the scrotum. Keep in mind that testicular cancer typically only causes symptoms in one testicle.


Although lumps and swelling caused by cancer are usually painless, the testicles themselves may become painful when cancer is present. Pain may also be felt in the scrotum. Cancer-related pain can occur independently of swelling—this means that testicular pain caused by cancer can happen even if there is no lump present, which is why reporting testicular pain to your doctor is important, even if there are no other symptoms present.


Gynecomastia is a condition in which breast tissue in men grows. In some cases, testicular cancer triggers the release of hormones that cause gynecomastia to occur. When this happens, men may experience breast growth or tenderness in the breast area.
