2,6,14) Improved detection of
adenomatous polyps during colonoscopy provides greater potential for prevention of colorectal cancer through polypectomy.
Most common neoplastic polyps are adenomas or
adenomatous polyps, which arise due to dysplastic proliferation and have a potency to progress to cancer.
If you've already had a polyp found and removed during a colonoscopy, if anyone in your family has had colon cancer or
adenomatous polyps, if you have irritable bowel disease or genetic predispositions or if you are black or an Ashkenazi Jew, you may want to get the DNA stool test every year; you'll need to have a colonoscopy as frequently as your doctor recommends.
Cannon-Albright LA, Skolnick MH, Bishop DT, Lee RG, Burt RW--Common inheritance of susceptibility to colonic
adenomatous polyps and associated colorectal cancers.
He presented with rectal bleeding at 14 years of age and a pedunculated
adenomatous polyp was identified on colonoscopy and removed.
The risk applies to all types of colonic neoplasms and appears to increase with advancing stage of the neoplasm from hyperplastic and
adenomatous polyps to tubulovillous adenoma, adenoma with high-grade dysplasia, and adenocarcinoma.
While daily aspirin use has also been convincingly shown to reduce the risk of colorectal cancer and recurrence of
adenomatous polyps, these benefits alone do not outweigh harms from aspirin-induced bleeding in average-risk populations.
Adenomatous polyps are well-described precursor lesions of invasive colorectal cancer and can be effectively managed by endoscopic intervention.
Esrailian goes on to say that there are many reasons why earlier screening or a shorter interval would be justified, such as the presence of
adenomatous polyps.
There are several types of polyps, the most common being hyperplastic polyps,
adenomatous polyps and malignant polyps.
Majority (78%) of polyps were in the rectosigmoid colon and all were juvenile hamartomatous polyps except two which were
adenomatous polyps.
Patients with a first-degree relative diagnosed with colorectal cancer (CRC) or
adenomatous polyps (AP) after the age of 60 have an increased risk and should start screening at 40 years of age, the article recommends.
