The polyp was removed by snare cautery. 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. Gastric juvenile polyp – 2 – very low mag. Inflammatory fibroid polyp – intermed mag.

Colon polyps are not commonly associated with symptoms. Occasionally rectal bleeding, and on rare occasions pain, diarrhea or constipation may occur because of colon polyps. Most colon polyps can be categorized as sporadic. Micrograph of a Peutz-Jeghers colonic polyp – a type of hamartomatous polyp. 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. 60 will have at least one adenomatous polyp of 1 cm diameter or greater.

1 cm in diameter, and have a small potential for malignancy. Villous adenomas are commonly found in the rectal area and they are normally larger in size than the other two types of adenomas. They tend to be non-pedunculated, velvety, or cauliflower-like in appearance and they are associated with the highest morbidity and mortality rates of all polyps. The risks of progression to colorectal cancer increases if the polyp is larger than 1 cm and contains a higher percentage of villous component. Also, the shape of the polyps is related to the risk of progression into carcinoma. Although polyps do not carry significant risk of colon cancer, tubular adenomatous polyps may become cancerous when they grow larger.

Larger tubular adenomatous polyps have an increased risk of malignancy when larger because then they develop more villous components and may become sessile. At this point, there is no method to establish the risks that patients with a family history of colon polyps have to develop these growths. Screening for colonic polyps as well as preventing them has become an important part of the management of the condition. Medical societies have established guidelines for colorectal screening in order to prevent adenomatous polyps and to minimize the chances of developing colon cancer. According to the guidelines established by the American Cancer Society, individuals who reach the age of 50 should perform an occult blood test yearly. Colon polyps as they grow can sometimes cause bleeding within the intestine, which can be detected with the help of this test. It has been statistically demonstrated that screening programs are effective in reducing the number of deaths caused by colon cancer due to adenomatous polyps.

While there are risks of complications associated with colonoscopies, those risks are extremely low at approximately 0. For comparison, the lifetime risk of developing colon cancer is around 6 percent. A cervical polyp is a common benign polyp or tumor on the surface of the cervical canal. Nasal polyps are polypoidal masses arising mainly from the mucous membranes of the nose and paranasal sinuses. They are overgrowths of the mucosa that frequently accompany allergic rhinitis. They are freely movable and nontender.

Polyps on the vocal folds can take on many different forms, and can sometimes result from vocal abuse, although this is not always the cause. Most polyps are larger than nodules, which are more similar to callouses on the vocal folds. If an individual experiences symptoms for more than 2 to 3 weeks, they should see a physician. Polyps may be treated with medical, surgical, or behavioral intervention. Surgical intervention involves removing the polyp from the vocal fold. In children, surgical intervention is rare.
