Testicular Cancer 

Testicular cancer is relatively rare, affecting over 2,000 men every year, but the numbers are increasing. It is also the most common cancer in young men. Fortunately, it is rarely fatal, well under 100 men die from testicular cancer each year in the UK. It is one of the most treatable cancers, especially if caught early.


A lump on a testicle, enlargement or swelling of the scrotum, or a dull ache or pain felt in the testes.

Symptoms often present in only one testicle. Men should not assume they have cancer if they have any of the described effects, as these symptoms are often due to other less threatening causes.

The key symptoms to look out for are: 

  • A lump in either testicle
  • Any enlargement of the testicle
  • A feeling of heaviness in the scrotum
  • A dull ache in the abdomen or groin
  • A sudden collection of fluid in the scrotum
  • Enlargement or tenderness of the breasts


It's important to remember that testicular cancer may not cause any discomfort or pain, especially in the early stages. The most common symptom is a small painless lump.

Any of these symptoms can also have benign (i.e. non-cancerous) causes, but they should always be checked by a doctor.
