Cancer of the testicles, also known as testicular cancer, is one of the less common cancers. It usually affects younger men between the ages of 15 and 49.
The most common symptom is a painless lump or swelling in the testicles. Other symptoms can include:
It's important for a man to be aware of what feels normal. Guys, get to know your body and see your GP if you notice any changes.

The testicles are the two oval-shaped male sex organs that sit inside the scrotum on either side of the penis.
The testicles are an important part of the male reproductive system because they produce sperm and the hormone testosterone, which plays a major role in male sexual development.
Types of testicular cancer. The different types of testicular cancer are classified by the type of cells the cancer first begins in.
The most common type of testicular cancer is known as ‘germ cell testicular cancer’, which accounts for around 95% of all cases. Germ cells are a type of cell that the body uses to help create sperm.
There are two main subtypes of germ cell testicular cancer. They are:
Less common types of testicular cancer include:
How common is testicular cancer? Testicular cancer is relatively uncommon, accounting for just 1% of all cancers that occur in men.
Each year in the UK around 2,300 men are diagnosed with testicular cancer, according to Cancer Research UK.
Testicular cancer is unusual compared to other cancers because it tends to affect younger men. As a result, although relatively uncommon overall, testicular cancer is the most common type of cancer to affect men between the ages of 15 and 49.
Rates of testicular cancer are five times higher in white men than in black men. The reasons for this are unclear.
The number of cases of testicular cancer that are diagnosed each year in the UK has roughly doubled since the mid-1970s. Again, the reasons for this are unclear.
The causes of testicular cancer are unknown, but a number of things have been identified that increase the chance of developing the condition. These include:

Outlook Testicular cancer is one of the most treatable types of cancer. More than 96% of men with early stage testicular cancer will be completely cured.
Even cases of more advanced testicular cancer, where the cancer has spread outside the testicles to nearby tissue, have an 80% chance of being cured.
Treatment for testicular cancer includes the surgical removal of the affected testicle (which should not affect fertility or the ability to have sex), and chemotherapy. Less commonly, radiotherapy (a treatment that uses radiation to kill cancer cells) may be used for seminomas.
