What Percentage Of People Have Colon Polyps
What percentage of lynch syndrome patients develop colon polyps by age 60? Not cancer but just polyps
Colon ca, not polyps: Lynch syndrome affects a minority of patients, as it is a rare condition that is often inherited (in about 30% of pts). Of these pts, about 70% will develop colon cancer - most of them by age 60. The risk is high. But the syndrome causes NON-polyp colon cancer, not polyps. It usually requires colon removal (colectomy) to reduce risk. Use HealthTap Prime or talk to your gastroenterologist about sym ...Read more
Lots!: People have a 20-30% lifetime risk of growing a colon polyp! many never turn to cancer, and frequent checks should prevent most from turning to cancer by getting them out before they change, thus the recommendation for more frequent colonoscopies in those who have grown polyps before. Studies have clearly shown, colonoscopies prevent colon cancer! ...Read more
Abnormal gowths : Neoplasia is a general term to describe abnormal growth pattern, cancer-like, unregulated by normal bodily control systems. Some colon polyps are destined to become cancerous, some are not, so all polyps are usually removed when they are found so we can distinguish the difference under the microscope, not by appearance which can fool you. ...Read more
By scope vs. surgery: If your colon polyps are identified colonoscopically, they can be removed piecemeal by cold biopsy, or cauterized by wrapping a snare around the polyp & adding electricity. Even large polyps can be colonoscopically removed in their entirety by emr (endoscopic mucosal resection). Invasive adenomas, dysplastic polyps, & frank malignancies may require surgery (usually laparoscopic). ...Read more
Not typically: On occasion, polyps may infarct, twist on their stalk, bleed, or secrete (villous tumors of the rectum) with resulting "diarrhea." however, most polyps & colon cancers are identified (hopefully) before symptoms develop. Early detection at a smaller polyp size means higher cure rates, lower risk of malignant transformation or invasion, & improved survival before cancer develops. Get a colonoscopy! ...Read more
Prevention is key: Once you have been identified as a person in whom adenomas (pre-cancerous polyps) develop: 1) first remove the polyps; 2) schedule surveillance to rule out new polyp development; 3) prevention by behavior & diet. Current recommendations for the latter include: use of daily low-dose aspirin, weight management, reduction of dietary animal fats, optimized fiber intake, calcium supplementation. ...Read more
Not common, but can have different types of colon polyps.
Most common would be juvenile polyp. But cases with family history of familial polyposis will have higher incidence of adenomatous polyps (tubular adenoma).
In addition there are other rare types with various syndromes.

Possibly: We don't really know because most people don't get colonoscopies in their 20's. Most people start at age 50 for colon cancer screening. There are some inherited syndromes like Familial Polyposis that predispose someone to polyps, but they are exceedingly rare. The polyp should be biopsied to figure out what type it is, which will be very informative. ...Read more
These are some predisposing factors for colon poliposis which is related to colon cancer:
• hereditary nonpolyposis colorectal cancer (hnpcc, also known as lynch syndrome)
• familial adenomatous polyposis (fap)
• attenuated familial adenomatous polyposis (afap)
• myh associated adenomatous polyposis (map)
• peutz-jeghers syndrome (pjs)
• familial juvenile polyposis coli (fjp). ...Read more

Colon polyps: Diets high in fiber, calcium, antioxidants (as from broccoli/cabbage/ cauliflower/brussel sprouts; green leafy vegetables; brightly colored fruits and veggies) seem to lessen risk of colon cancer. A positive family history for polyps, however increases risk, as does personal history of polyps. Avoid highly processed foods and fast foods due to low nutrition, high preservatives, high fat. ...Read more
Variable: Exact rate;density of polyp growth to malignant transformation is virtually unknown due to so many variables, earlier studies the mean doubling time 130 days (53-1570) 5mm polyps increases size 5-9mmm mean mass decreases as some of the polyps spontaneously regress. If polyp is removed completely will not come back in the same spot. ...Read more
