Precancerous Colon Polyps
Mother had precancerous colon polyp at 40, father had noncancerous polyp at 40... when should I have first colonoscopy?
It depends on....: You may be at a higher risk for polyps than the average person where colonoscopy is advised at 50 years of age. For high risk it is advised at 40 years. But if you have any symptoms of blood loss or abdominal symptoms anytime, you should get your colon checked before you turn 40. If you want to be free of any anxiety, then do it sooner(now or during this year provided you can handle the expenses. ...Read more
A precancerous condition (or premalignant condition) is a generalized state associated with a significantly increased risk of cancer. If left untreated, these conditions may lead to cancer. Premalignant lesion is a morphologically altered tissue in which cancer is more likely to occur than ...Read more
What % of colon polyps removed come back as being pre-cancerous? My brother has colon cancer, my moms polyps were pre-cancerous. My odds of having?
Colon polyps : There are genetic tests for all varieties of family colon cancers. You may never have another problem, but you need to find out your relatives' type and get tested by a blood test. Look up other sources of familial colon cancer to do research to understand it better. Do not do nothing. Good luck to all of you. ...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 20s. 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 polyps spontaneously regress. If polyp is removed completely will not come back in the same spot. ...Read more
