Testicular cancer symptoms

The most common symptom of testicular cancer is a lump in a testicle. But there may also be other signs and symptoms:

• swelling in a testicle – this is usually painless, but it may sometimes suddenly get bigger and become painful
• a dull ache, pain or a feeling of heaviness in the scrotum.

If the cancer has spread to the lymph nodes or other parts of the body, it may cause:

• pain in the back or lower abdomen (tummy)
• weight loss
• a cough
• breathlessness
• feelings of being unwell
• a lump in the neck.

Rarely, the hormones the cancer makes can cause the nipples or breasts to feel tender. They can also cause breast swelling, which is called gynaecomastia.

Conditions other than testicular cancer may cause these signs and symptoms. But it is always important to get your symptoms checked by your doctor.
