Testicular cancer

Testicular cancer affects about 180 men in Ireland each year. It is more common in caucasians.

Testicular cancer is treated with surgery, chemotherapy and radiotherapy, depending on the type.

What is testicular cancer?

Testicular cancer is when the cells of your testicle grow in an abnormal way to form a lump (tumour). The cancer can affect how the testicles work normally. Sometimes testicular cancer cells spread to lymph glands at the back of the abdomen, the chest or neck. 

Testicular cancer is rare, but it’s the most common cancer in young men aged between 15 and 34. About 180 men are diagnosed with testicular cancer every year in Ireland.

Testicular cancer is very treatable and is nearly always curable.

What are the testicles and what do they do?

The testicles are part of the male reproductive system. They are also known as the testes. They are two small, egg-shaped organs found below your penis in a pouch of skin called the scrotum. Once you reach the age of puberty they make sperm.

The testicles lie outside your body because they need to be at a lower temperature than the body to make sperm. Sperm is needed to fertilise the female egg after sex, which will grow into a baby. The testes also make the hormone testosterone. This hormone is responsible for male qualities such as a deep voice, facial hair and strong muscles. It also gives you a sex drive and the ability to have an erection.
