Colorectal cancer screening
Colorectal (bowel) cancer is one of the most preventable cancers — because it usually starts as a growth that bleeds tiny amounts long before you feel anything.
Signs to watch for
- Blood in the stool (even if not visible)
- A lasting change in bowel habit
- Tummy discomfort or cramping
- Tiredness or unexplained weight loss
If symptoms are severe or persistent — or you notice bleeding or weight loss — see a doctor promptly.
Why a test helps
A simple, at-home stool test (FIT) can detect hidden blood — no diet restrictions, no scope needed to start. A positive result means a doctor arranges a colonoscopy to look closer.
