But if you have a first degree relative with either colon cancer or an adenomatous polyp, don't wait until you're 50 and start your regular screening by the age of 40, or at least 10 years younger than the affected relative.
Among the 65 colorectal polyps, 50 cases were adenomatous polyps and tubular adenomas constitute the predominant type of adenomatous polyp.
The most common type was the adenomatous polyp in 88(55.0%) cases followed by hyperplastic polyps 51(31.9%) and inflammatory polyps 21(13.1%).
Comparison of the metabolic profiles of human adenomatous polyp (N = 61) and colorectal cancer (CRC) (N = 57) tissue found statistically significant differences (p < 0.05) in their composition of adenosine monophosphate (AMP), adenine, 5'-methythioadenosine, 3-hydroxybutyric acid, prostaglandin E2, threonine, and glutamine.
* average risk of developing colorectal cancer (no personal history of adenomatous polyps, of colorectal cancer, or inflammatory bowel disease, including Crohn's Disease and ulcerative colitis; no family history of colorectal cancers or an adenomatous polyp, familial adenomatous polyposis, or hereditary nonpolyposis colorectal cancer).
A) 672 adults from the Nurses' Health Study and the Health Professionals Follow-up Study with a history of adenomatous polyp formation
Given that most sporadic CRCs develop from adenomatous polyps, it has been shown that CRC risk can be reduced by removal of the precursor lesion, the adenomatous polyp.

A PREVIOUS POLYP OR COLORECTAL CANCER: Not all types of polyps increase the risk of bowel cancer, but a type called adenomatous polyp does.
Results: The risk of adenomatous polyp recurrence was inversely related to alpha-carotene concentrations and right-sided polyps; alpha-carotene intake and recurrence of any, multiple and right-sided polyps; beta-carotene intake and multiple adenoma recurrence; and vitamin A from food and dietary supplements and each adverse endpoint.
For example, it takes an average of 15 to 20 years for a small adenomatous polyp to become malignant.
