Can gastroenterology provide colorectal cancer screening?

A gastroenterology team reviews your family history, previous findings, symptoms, medicines, and bowel health. Screening may use a stool test or a colonoscopy, depending on the situation and local clinical advice. A colonoscopy allows the bowel lining to be examined and may allow tissue samples or removal of a polyp during the same procedure. Screening is for people without concerning symptoms; symptoms may need diagnostic assessment instead.

Tell the team about bowel habit changes, blood in the stool, unexplained weight change, abdominal symptoms, family history, and previous colon tests. Provide a complete medicine list, especially blood thinners, and follow preparation instructions carefully if a colonoscopy is planned. Ask how results will be communicated and what follow-up is expected.

Contact a clinician promptly for visible blood in the stool, black stools, persistent change in bowel habit, ongoing abdominal pain, unexplained tiredness, or unintentional weight loss. Seek emergency help for heavy bleeding, fainting, severe abdominal pain, or a swollen abdomen with repeated vomiting. Do not rely on a routine screening appointment to assess rapidly worsening symptoms.

Ask which test is appropriate, how your family history changes the plan, what preparation involves, which medicines need special instructions, and when you should expect the result.
