If a person has any adenomas removed they will usually need ongoing screening to check for the development of more polyps or signs of bowel cancer. Several rare genetic conditions can cause bowel polyps to develop, and these have much greater risk of turning into cancer. For example, in people with familial adenomatous polyposis FAP , a hundred or more small polyps develop on the colon, so that it looks like a carpet of small raised lumps.
Several members of a family may suffer from this condition. Therefore, all people who have a relative with FAP should have regular bowel screening. Most people with FAP are advised to have their large intestine removed to prevent cancer. Because there are often no symptoms, bowel polyps are usually found during a bowel cancer screening test or a bowel investigation for another reason.
Most bowel polyps are found through a colonoscopy , which is a type of investigation that looks at all parts of the colon. A colonoscopy involves inserting a thin, flexible tube into the rectum. The tube known as a colonoscope, has a light and camera attached so that images can be relayed onto a screen and the doctor can see any polyps. The tube is long enough to examine the full length of the colon and also allows the doctor to take samples of tissue to examine or remove the polyp.
Sometimes, a bowel polyp is diagnosed with other tests such as a sigmoidoscopy like a colonoscopy, but uses a shorter tube to examine the rectum and lower part of the colon. People aged over 50 and those with a greater risk of developing polyps or bowel cancer require regular bowel screening to check for polyps and other changes in the bowel.
Bowel polyps are usually removed, even if they are not causing symptoms. This helps minimise the development of bowel cancer. Bowel polyps can be removed during a colonoscopy. Duriing the procedure, the doctor manoeuvres a long wire loop through the colonoscope and around the base of the polyp. The loop is pulled tight, cutting off the polyp. After removal, the polyp is sent to a pathology lab to check for any signs of cancer. The lab will also be able to tell if the polyp has been entirely removed or if there is a chance of it growing back.
A person can lower their risk of developing bowel polyps by having regular check-ups and taking part in recommended bowel screening programs.

Types of bowel polyps The 2 most common types of polyps are adenomas and hyperplastic polyps. Adenomas adenomatous polyps : These are usually small, less than one cm in diameter; there is a small risk that they will develop into cancer; most bowel cancers develop from an adenoma that has been present for 5 to 15 years.
Hyperplastic polyps : these polyps are very small, usually less than half a centimetre in diameter; generally considered harmless as they do not usually develop into cancer, except very rarely.
What are the symptoms of bowel polyps? Some options include cold forceps polypectomy, hot forceps polypectomy, and snare polypectomy. Once a surgeon removes the polyp, they may send it to a pathologist. This is a doctor that specializes in finding the origin of diseases. They will examine the polyp using a microscope to determine the type of polyp and whether it is or can become cancerous. If a person has a history of polyps, they are likely to develop more in the future.
This may increase their risk of developing cancerous polyps. Therefore, after a person has polyps removed, a doctor may monitor them more closely and test them more frequently. Typically, colon polyps are harmless and not a cause for concern. However, people should speak with a healthcare professional if they experience any of the following symptoms:.
People should also consult a doctor if any of the following symptoms occur following the removal of polyps:. Colon, rectal, or bowel polyps are fairly common and typically harmless. However, certain types, such as adenomatous polyps, can become cancerous and will likely require removal. People should speak with a doctor if chronic bowel habit changes occur or if blood appears in the stool, on toilet paper, or on underwear.

Definition Shapes Types Complex polyps Treatment Contacting a doctor Summary Colon polyps are small growths of tissue that project from the lining of a section of the large intestine known as the colon. Colon polyp definition. Different shapes. Types of colon polyps. What are complex polyps? Most of these colon polyps are called adenomas.
Serrated polyps may also become cancerous, depending on their size and location in the colon. In general, the larger a polyp, the greater the risk of cancer, especially with neoplastic polyps. Rarely, people inherit genetic mutations that cause colon polyps to form. If you have one of these genetic mutations, you are at a much higher risk of developing colon cancer. Screening and early detection can help prevent the development or spread of these cancers. Some colon polyps may become cancerous.
The earlier polyps are removed, the less likely it is that they will become cancerous. You can greatly reduce your risk of colon polyps and colorectal cancer by having regular screenings.
