Family history of bowel cancer
Frequently Asked Questions
My grandparent had bowel cancer. Am I at higher risk?expand_more
Usually not by much, especially if they were diagnosed later in life. We look at the whole family pattern rather than one relative alone.
When should I have my first colonoscopy?expand_more
It depends on your risk group. For many people, this is a single colonoscopy at 55. Some people need no extra checks, and higher-risk families start earlier.
Do I need genetic testing?expand_more
Only if your family history suggests an inherited condition, or a relative has already tested positive. We will refer you to an NHS clinical genetics service when this applies.
My relative had polyps, not cancer. Does that count?expand_more
Polyps are common and usually do not raise your risk on their own. Tell us anyway, as many polyps in one family can point to an inherited condition.
Is a colonoscopy safe?expand_more
Colonoscopy is a safe test, but it carries small risks, including bleeding and, rarely, a tear in the bowel wall. We only recommend one when the benefit for you outweighs the risk.
