After a 2003 angiogram I was prescribed aspirin and a variety of other meds.  I take the aspirin (85mg) dose daily and seem to have no problems.  Yesterday I had a colonoscopy (colon cancer runs in my family) and I appear to be the first to not have polyps removed.  May be a coincidence, but I understand that aspirin may reduce the chance of colon cancer.
Like any drug, it should be used in accordance with your doctor's advice.  It's not a cure-all, but it may be a low cost tool to reduce some of the health risks.
