What are symptoms of testicular cancer?

The most common symptom of testicular cancer is a lump, or swelling, in one of your testicles. Testicular lumps are most commonly found on either the front, or the side, of the testicle. They often feel like a hard, pea-sized swelling. Testicular cancer can also cause other symptoms, including: * a dull ache, or sharp pain, in your testicles, or scrotum, which may come and go, * a feeling of heaviness in your scrotum, * a dull ache in your lower abdomen, * a sudden collection of fluid in your scrotum (hydrocele), * fatigue, and * generally feeling unwell.
