Hemorrhoids or Colorectal Cancer?

    Because both can cause rectal bleeding, patients frequently worry about this distinction. Symptoms overlap, and the two conditions can also coexist, which is why self-diagnosis is unreliable.

    Findings more suggestive of hemorrhoids

    • Bright red blood on the paper or dripping after defecation
    • Itching, a sensation of swelling or a reducible lump
    • Symptoms fluctuating with constipation or straining

    Findings that require prompt investigation

    • Blood mixed within the stool or dark, tarry stools
    • Persistent change in bowel habit or pencil-thin stools
    • Unintended weight loss, fatigue or anaemia
    • New symptoms at or after the age of 45
    • Family history of colorectal cancer or polyps

    Why both can be present

    Finding hemorrhoids on examination does not exclude a lesion higher in the colon. When risk factors or alarm features are present, colonoscopy is advised even if hemorrhoids are visible.

    Frequently asked questions

    Can hemorrhoids turn into cancer?
    No. Hemorrhoids do not transform into cancer, but they can mask symptoms of another condition.
    Do I need colonoscopy if hemorrhoids are found?
    It depends on age, risk factors and whether alarm features are present; the decision is individual.
    How quickly should I be seen?
    Alarm features warrant prompt assessment rather than watchful waiting.
