The main symptom of bladder cancer is blood in your urine. This is the same for both men and women.

Blood in the urine

Blood in the urine is the most common symptom of bladder cancer. 8 out of 10 people with bladder cancer (80%) have some blood in their urine. Doctors call blood in the urine haematuria (pronounced heem-at-you-ree-ah).

You may see the blood in your urine. It usually looks bright red. Rarely, it may look dark brown.

Sometimes the blood is there in such small amounts that you can't see it. But a urine test will pick it up.

The blood may not be there all the time. It can come and go. But if you ever see blood in your urine, you should go to your GP.

The bleeding is not usually painful. But it can help your doctor to know whether you had any pain when you passed the urine with the blood in it.

It can also help if you tell them whether: 

  • there is blood only when you start to pee
  • the blood is mixed with all the urine you pass

Other symptoms of bladder cancer

Other symptoms of bladder cancer can include:

  • passing urine very often (frequency)
  • passing urine very suddenly (urgency)
  • pain or a burning sensation when passing urine
  • weight loss
  • pain in your back, lower tummy or bones
  • feeling tired and unwell

These symptoms are much more likely to be caused by other conditions rather than cancer. For example a urine infection, particularly if you do not have blood in your urine. For men, the symptoms could be caused by an enlarged prostate gland. 

But do tell your doctor straight away if you have these symptoms. If you have an infection, it can usually be cleared up very quickly with antibiotics. And it is always best to check for cancer as early as possible so that it can be diagnosed while it is easier to treat.

When to see your doctor

You should see your GP if you have any of these symtpoms. But remember, they can all be caused by other medical conditions. Most people with these symptoms dont have bladder cancer.
