January 2012: Daily dose of aspirin may do more harm than good: study

British researchers have found the risk of internal bleeding caused by daily aspirin outweighed potential benefits. The study of 100,000 healthy people who have taken aspirin, the largest of its kind, found that while one heart attack or stroke was averted for every 120 people treated with aspirin over a six-year period, one in 73 people suffered potentially significant bleeding. The researchers at St George's, University of London, recommended that people who have suffered a heart attack or stroke and are therefore at a high risk of another should still be routinely prescribed aspirin. However, they raised concerns about the millions of otherwise healthy people taking aspirin in an attempt to prevent their first heart attack or stroke. The study also found that the risk of dying from cancer was not affected, despite recent studies showing that the drug could prevent bowel cancers.
