If you notice blood in your pee, even if it's just the once, tell your doctor.

Dr Philip Sawyer

If you notice blood in your pee, even if it's just the once, tell your doctor. Chances are it's nothing serious, but you're not wasting anyone's time by getting it checked out. Call your GP today.

What could it be?

Some symptoms may be caused by an infection or bladder or kidney stones, all of which may need treatment. But don't try and diagnose yourself. Go and see your doctor now to find out for sure.

Also, if you’ve been to the doctor but your symptoms haven't gone away, he or she will want to know. It's important to see your doctor again if your symptoms persist.

Could it be cancer?

Blood in your pee can also be a sign of bladder cancer or kidney cancer, which is why it's so important to see your doctor straight away. Early detection makes it easier to treat. Seeing your doctor could save your life.

Acting quickly probably saved my life. In fact, it's given me a new lease of life.

Dr Dawn Harper explains what to look for

Are there other symptoms of bladder or kidney cancer?

Blood in your pee is a key symptom for both types of cancer, but other symptoms include:

Bladder cancer:

  • cystitis (a urinary tract infection) that is difficult to treat or comes back quickly after treatment
  • pain while peeing

Kidney cancer:

  • a pain in the side, below the ribs, that doesn’t go away
  • weight loss

If you have any of these symptoms, see your GP as soon as possible. If you know anyone who has any of these symptoms, insist they see their doctor.

What will happen at my GP appointment?

You're not wasting anyone's time by getting your symptoms checked out, and if it's not serious, your mind will be put at rest.

At your appointment, your GP may ask about your symptoms, family history and whether you've been exposed to any possible causes of bladder or kidney cancer, such as smoking.

In some cases, your GP may request a urine sample, so it can be tested in a laboratory for traces of blood and bacteria.

Your GP may also carry out a physical examination.

If your doctor suspects cancer, you'll be referred to a hospital for further tests.

About bladder and kidney cancer

Around 17,450 people in England are diagnosed with bladder or kidney cancer each year. Both cancers affect men and women, although they are more common in men. Most people diagnosed with bladder and kidney cancers are over 50, although people of all ages can be affected.

Smokers have a much higher risk of these cancers. Other things that increase your risk of getting bladder or kidney cancer include:

  • being overweight or obese
  • some jobs, because of exposure to certain chemicals
  • other medical conditions, such as kidney failure
  • a family history of cancer

Reduce your risk

A healthy lifestyle can help you reduce your risk of bladder cancer or kidney cancer. Some ways to stay healthy are:

  • stop smoking – if you smoke, the best thing you can do for your health is to quit. There's plenty of support available from the NHS. Visit nhs.uk/smokefree or call 0300 123 1044.
  • look after yourself – try to maintain a healthy weight and keep active. Swimming, cycling, dancing, walking – the more you can do, the better. Try to eat a healthy, balanced diet too, with plenty of fruit and vegetables.
  • cut down on alcohol – drinking too much alcohol can lead to a number of health problems. By drinking less, you'll reduce your health risks.
