Symptoms and Signs of Testicular Cancer

Doctor's Notes on Testicular Cancer

Testicular cancer is an abnormal growth of malignant (cancerous) cells in the testicles or testes, which are the male reproductive organs where sperm are produced. Testicular cancer usually occurs in only one testicle. Testicular cancer can occur at any age, but it is the most common type of cancer in young men aged 15 to 35, and it is one of the most curable of all cancers.

Symptoms of testicular cancer include painless swelling, a lump (may be small like pea-sized, or large like a marble or bigger), or pain in a testicle. The lump may be small or large. Less common symptoms of testicular cancer include a lasting ache, a sensation of heaviness in the testicle, significant shrinking of a testicle, a hardness of the testicle, or a dull ache or fullness in the abdomen, pelvis, or groin is the only symptom. In rare cases the first symptom of testicular cancer may be breast tenderness.
