Aspirin Reduces Risk of New Polyps

Taking either high or low dose aspirin reduces the chances the people with colorectal polyps (adenomas) will get more.

A combined analysis of three randomized controlled trials that compared taking aspirin to a placebo after adenomas were removed found that people who took a daily low dose or baby aspirin had almost a 20 percent lower chance of another adenoma during their next colonoscopy.  High-dose or regular adult strength aspirin reduced risk of polyp recurrence by about 15 percent.

Any aspirin reduced the risk of advanced adenomas by more than 35 percent. Continue reading…

Two Colonoscopies Better at Predicting Future Polyp Risk

Results from two colonoscopies three years apart gave better information about whether a high-risk polyp would be found on a third exam than results from the second test alone.

Even if a second colonoscopy, done three years after the first, showed no adenomas at all, 8 in 100 study participants with high-risk polyps on their first exam had developed a high-risk polyp by six years when they had a third colonoscopy. Continue reading…

Vitamin D Reduces Risk for Colon Polyps

Both the level of vitamin D in the blood and intake of vitamin D-rich foods decrease the risk of colorectal polyps in a number of studies.

Analyzing published studies of blood levels of vitamin D, researchers found a 30 percent decrease in the risk of adenomas among people with the most circulating vitamin D compared to those with the least.  The highest vitamin D intake decreased adenomatous polyp risk by 11 percent. Continue reading…
