The main symptoms are:

  • A lump or a swelling in a testicle (that’s usually painless) is the most common symptom. Occasionally the swelling suddenly increases and becomes painful.
  • Pain or a feeling of heaviness in the scrotum (sac that holds the testicles).

There might also be other symptoms if the cancer has spread: 

  • Pain in your back, groin or lower tummy - this is if the cancer has spread to the lymph nodes at the back of the tummy.  
  • Tender or swollen nipples - this isn’t common but can be caused by hormones produced by the cancer.

Most lumps and swellings, especially in the epididymis (the tube at the top behind the testicle) aren’t cancer. But it’s important to get any lump or swelling or any of the other symptoms here checked by your family doctor straight away.

Some guys find it difficult to tell their parent(s) or guardian(s) about a problem to do with their private parts. But it’s important to try to talk to them - they’ll want to help and support you as much as they can.

If you really feel you can't talk to them, you can see your doctor on your own. You don't have to say what’s wrong when you make an appointment - if anyone asks tell them it's private. Doctors are used to dealing with problems to do with private parts of the body, so try not to feel embarrassed.

If you don’t want to see your doctor, you can get checked out at your local sexual health clinic where you don't have to give your name. You can find the number online or in your local phone book.

The important thing is to make sure you get any symptoms checked out by a doctor straight away.

Remember - testicular cancer can nearly always be cured and it’s easier to treat when it’s found early.
