You can't always see the signs! Bowel cancer is the third most common cancer in the UK. The earlier it's found, the more effectively it can be treated.
If you are aged 50-74 you will automatically be sent a free bowel screening kit. If you are over 74, you can request a kit by calling 0800 0121 833.
More information on the programme can be found on the Bowel Screening website.
