Around 2,000 men, usually young or middle aged, are diagnosed with testicular cancer in the UK each year but treatment is very effective, and nearly all men are cured.
Also known as germ cell tumours, the most common types of testicular cancer are seminomas and non-seminomatous germ cell tumours (NSGCTs), which are also known as teratomas.
The causes of testicular cancer are unknown, but factors such as family history, an undescended testicle, and abnormal cells can increase the chance of getting testicular cancer. Tall men, white men and wealthier men also appear to have a higher risk, although it’s not clear why.
Things to look out for
The most common symptom is a lump or swelling in a testicle. This is usually painless but may suddenly increase in size and become painful. Other symptoms can include pain or heaviness in the scrotum. These symptoms can be caused by other conditions but it’s important to have them checked by your doctor.
Testicular cancer is usually curable, especially if it is diagnosed early. For this reason it’s important that you check your testicles regularly for any lumps or swellings and see your doctor about anything unusual as soon as possible.
