Bowel cancer is usually treatable if it's found early enough. Unfortunately, even when bowel cancer is treated, there's sometimes a chance that the cancer could spread or come back.

In more advanced cases, symptoms may be controlled and the spread of the cancer may be slowed using a combination of treatments.
