The facts
Mostly affecting men aged 15—45, testicular cancer is one of the most curable cancers if caught early. That’s why we recommend monthly self-checks.



Testicular cancer is the most common cancer among UK men aged 15—49. The highest incidence rates are among men aged 30—34.

Testicular cancer cases have increased by more than 27% since the early ’90s.

2,400 men are diagnosed in the UK each year. That’s more than 6 men per day!

Survival rates for testicular cancer have risen every year since the ’70s.

If detected in its early stages, testicular cancer is 98% curable.


The most common signs of testicular cancer are:

Heaviness in the scrotum
Build-up of fluid in the scrotum
Pain / discomfort in the testicles or scrotum
Pain in the lower back

Usually these symptoms are caused by nothing more than injury or infection. But if you notice any of of these signs — or a combination of them — speak to your doctor to make sure. Knowing what’s normal for you will help you spot changes.


Risk factors

Undescended testicles
Men with undescended testicles which were corrected after the age of 11—13, or which have never been corrected, may be at greater risk.

Low fertility

Men with fertility problems have an increased risk of testicular cancer.

Family history

Having a brother and/or father who has had testicular cancer increases your risk. Research continues to investigate which genes are responsible.


Men who are taller than average have an increased risk of testicular cancer.

Previous diagnosis
A small number of men who have previously been treated for cancer in one testicle may go on to develop cancer in the other.

The myths
There are lots of false facts out there about testicular cancer. Here are some you can ignore.


“Injury can cause testicular cancer.”
Testicular cancer is not triggered by getting hit in the testicles. However, if you find any kind of lump or swelling following an accident, you should ask your GP to check it over.

“Vasectomy can cause testicular cancer.”
There’s no connection between vasectomy and cancer.

“I might catch testicular cancer.”
Testicular cancer is not infectious. It can’t be caught or passed on to other people.
