A bowel polyp is a small growth on the lining of the large bowel or rectum. Polyps are common, and most do not cause problems, but some types can become cancerous over time if left in place. For this reason polyps found during a colonoscopy are usually removed and sent to a laboratory for examination.
What Is a Bowel Polyp?
Polyps are growths that project from the inner lining of the colon or rectum. They are more common with age. Most cause no symptoms and are found during a colonoscopy done for screening or another reason.
Can a Polyp Become Cancer?
Polyps do not usually turn into cancer. One type, the adenoma, can become cancerous over many years if it is not removed, and most bowel cancers develop from adenomas. The larger a polyp, the greater the likelihood that it is cancerous or may become so.
How Are Polyps Removed?
Polyps found during a colonoscopy are often removed at the same time. This is called a polypectomy. A common method uses a fine wire loop to remove the polyp.
What Happens After Removal?
The polyp is examined in a laboratory. The report shows the type of polyp, whether it was completely removed and whether there is any cancerous change. Your doctor discusses the result with you.
Whether you need a follow-up colonoscopy, and when, depends on the number, size and type of polyps removed. Your doctor will advise you on this individually.
Frequently Asked Questions
Does finding a polyp mean I have cancer?
No. Most polyps are not cancer. The laboratory report confirms the type of polyp and whether there is any cancerous change.
Did I have symptoms from the polyp?
Most polyps cause no symptoms. Larger polyps can cause bleeding from the bottom, a change in bowel habit or abdominal pain.
Will I need another colonoscopy?
That depends on the number, size and type of polyps. Your doctor will advise whether and when a follow-up colonoscopy is needed.
Can polyps come back?
New polyps can develop in some people, which is why follow-up colonoscopy may be advised.
If you have questions about your colonoscopy results, please arrange a consultation with Dr. Loots. More about the procedure is in What to Expect From a Colonoscopy.
