1. B: Bleeding

There are several possible causes of bleeding from your bottom, of blood in your poo.

Bright red blood could come from swollen blood vessels, haemorrhoids or piles, in your back passage.

Dark red or black blood could come from your bowel or stomach.

Blood in your stools is one of the key signs of bowel cancer, so it’s important to mention it to your doctor so they can investigate.

2. O: Obvious change in loo habits

It’s important to tell your GP if you have noticed any changes in your bowel habits, that lasts three weeks or longer.

It’s especially important if you have also noticed signs of blood in your poo.

You might notice you need to go to the loo more often, you might have looser stools or feel like you’re not going enough or fully emptying your bowels.

Don’t be embarrassed, your GP will have heard a lot worse! Speak up and get it checked.

3. W: Weight loss

This is less common than the other symptoms, but an important one to be aware of. If you’ve lost weight and don’t really know why, it’s worth mentioning to your GP.

You may not feel like eating, feel sick, bloated and not hungry.

4. E: Extreme tiredness

Bowel cancer that causes bleeding can cause a lack of iron in the body – anaemia. If you develop anaemia you’re likely to feel tired and your skin might look pale.

5. L: Lump or pain

As with lots of other forms of cancer, a lump or pain can be a sign of bowel cancer.

It’s most likely you’ll notice a pain or lump in your stomach or back passage.

See your GP if it doesn’t go away, or if it affects how you eat or sleep
