Proctology
Anal polyps are small growths that form on the lining of the anus or lower rectum. They are usually benign adenomas (non-cancerous) but should always be evaluated by a doctor, as some types of polyps can develop into cancer over time. They are by definition a low grade dysplastic (atypical behaviour) lesion with the potential for progression of the dysplasia to an invasive malignancy. These lesions can be pedunculated (mushroom-shape), or “sessile” with board base. They can occur singly or as multiple lesions. They can vary greatly in size and extent. Anal polyps are often discovered during a colonoscopy or rectal examination, since many people don’t notice symptoms.
Some anal polyps cause no symptoms, but when they do, they may include:
If you experience bleeding or other symptoms, it’s important to have them checked — not all rectal bleeding is due to hemorrhoids.
Polyps can form due to abnormal growth of cells in the anal or rectal lining.
Common risk factors include:
The treatment depends on the type, size, and location of the polyp. Options include:
Regular screening and colorectal evaluation are essential to prevent recurrence or detect any early malignancy.
Visit your doctor if you have:
Anal polyps are usually harmless but must be diagnosed and removed safely to rule out any precancerous changes.
Early screening and expert care make all the difference.
