There is evidence that a daily regimen of low-dose aspirin (what used to be called “baby aspirin”) can reduce the risk of a first heart attack or stroke in those between the ages of 50 and 69. There is also some evidence that it may reduce the risk of colon cancer. Experts warn that such a regimen should only be undertaken by those with a high risk of heart disease and a low risk of bleeding.
As with any drug, do not begin a regimen of low-dose aspirin without consulting your doctor.
