Frequently Asked Questions
Are rectal polyps cancerous?
Most rectal polyps are benign, but some types can develop into cancer if left untreated. Early detection and removal help lower your risk.
What causes rectal polyps?
Factors include age over 50, family history of polyps, inflammatory bowel diseases, a low-fiber/high-meat diet, smoking, and heavy alcohol use.
How can I tell if it's a hemorrhoid or a polyp?
Both can cause bleeding, but only a thorough exam and colonoscopy by Dr. Scott can definitively distinguish between them.
Why do rectal polyps bleed?
Polyps are soft growths that can be irritated by stool or straining, causing them to bleed.
How often do I need screening?
Screening intervals depend on your personal and polyp history. Dr. Scott will recommend a schedule-often every 3-10 years-based on your findings.
Can I prevent polyps with diet?
Yes. A diet high in fiber (fruits, vegetables, whole grains) and low in red/processed meats, along with regular exercise, may help reduce your risk.
Is polyp removal painful?
No. Removal is performed during a sedated colonoscopy, so most patients experience little to no discomfort.
