are sessile polyps cancerous
Most polyps do not cause symptoms. But large polyps are more likely than small polyps to cause symptoms such as rectal bleeding. Some polyps are attached to the wall of the colon or rectum by a stalk or stem (pedunculated). Some have a broad base with little or no stalk (sessile).By Healthwise Staff.ut large polyps are more likely than small polyps to cause symptoms such as rectal bleeding. Some polyps are attached to the wall of the colon or rectum by a stalk or stem (pedunculated). Some have a broad base with little or no stalk (sessile). A polyp is an abnormal growth of tissue projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated. If no stalk is present, it is said to be sessile.Polyps are commonly found in the colon, stomach, nose, sinus(es) , urinary bladder and uterus.They may also occur elsewhere in the body where mucous membranes exist like the cervix, vocal folds, and small intestine.ain article: Familial adenomatous polyposis. Adenomatous polyps, or adenomas, are polyps that grow on the lining of the colon and which carry a high risk of cancer. The adenomatous polyp is considered pre-malignant, i.e., likely to develop into colon cancer. Regular screenings for colon polyps are the best way to prevent polyps from developing into colon cancer. Most colon polyps can be identified and removed during a colonoscopy. If you have had one or more adenomatous polyps removed, you probably need regular follow-up colonoscopy exams every 3 to 5 years.hese large polyps sometimes cannot be removed safely during a colonoscopy and may be more likely to develop into cancer. If cancer is found when the colon polyps are examined, you will begin treatment for colorectal cancer. For more information, see the topic Colorectal Cancer. Sessile polyps are common in HNPCC (hereditary nonpolyposal colon cancer) and colon cancers in people with these genetic mutations can develop very rapidly within 6 mos to 18 mos; whereas random colon cancer usually takes over 5 years to 10 years to develop from a polyp.essile polyps are common in HNPCC (hereditary nonpolyposal colon cancer) and colon cancers in people with these genetic mutations can develop very rapidly within 6 mos to 18 mos; whereas random colon cancer usually takes over 5 years to 10 years to develop from a polyp. Polyps can be cancerous (malignant) or not cancerous (benign). Here are the types of colon polyps. Pedunculated Polyp This type of polyp is when it is attached to the mucous membrane and has a narrow stalk of tissue.This is one of the most common types of colon polyps.Sessile Polyp When there is no stalk of tissue present and the polyp grows right on the mucous membrane, it is called sessile.edunculated Polyp This type of polyp is when it is attached to the mucous membrane and has a narrow stalk of tissue. This is one of the most common types of colon polyps. Sessile Polyp When there is no stalk of tissue present and the polyp grows right on the mucous membrane, it is called sessile. A polyp is a projection (growth) of tissue from the inner lining of the colon into the lumen (hollow center) of the colon. Different types of polyps look different under the microscope. Polyps are benign (non-cancerous) growths, but cancer can start in some types of polyps.errated polyps have a saw tooth appearance under the microscope and that is why they are called serrated. Some polyps are called traditional serrated, these look a little different under the microscope. Both types need to be removed from your colon. These polyps do not become cancerous. In this case you can continue your regular screenings, unless you are at an increased risk for colon cancer because of a family history of colon cancer or an inherited polyp syndrome. A sessile polyp doesn't have a stalk. It is mostly a flat growth.hese large polyps sometimes cannot be removed safely during a colonoscopy and may be more likely to develop into cancer. If cancer is found when the colon polyps are examined, you will begin treatment for colorectal cancer. For more information, see the topic Colorectal Cancer. The bigger a colon polyp is, especially if it is larger than 1 cm (0.4 in.) , the more likely it is that the polyp will be adenomatous or contain cancer cells. If only hyperplastic polyps are found during your flexible sigmoidoscopy, you likely do not need to have a colonoscopy.hese large polyps sometimes cannot be removed safely during a colonoscopy and may be more likely to develop into cancer. If cancer is found when the colon polyps are examined, you will begin treatment for colorectal cancer. For more information, see the topic Colorectal Cancer. Polyps can be classified by what type of cells they develop from, or by their appearance. This is a picture of a pedunculated polyp. This polyp has a stalk beneath it. It is a large polyp which was causing the person to have bright red blood with bowel movements. This is a picture of a flat or sessile polyp.These polyps can be difficult to spot if the colon is not properly cleaned. Depending on what cells a polyp has develped from, some polyps will grow rather quickly and carry a greater risk of developing colon cancer.his is a picture of a flat or sessile polyp.

Most benign sessile colon polyps can be removed colonoscopically from all reaches of the colon, thus avoiding laparotomy previously required for most of these lesions. Two hundred and fifty colonoscopy procedures were reviewed, revealing 87 sessile colon polyps ranging from 0.5-6.0 cm. in size.ost benign sessile colon polyps can be removed colonoscopically from all reaches of the colon, thus avoiding laparotomy previously required for most of these lesions.
