Using Aspirin to Prevent Cancer

Benefits and Risks

Many people at risk for heart disease have been told to take aspirin daily to prevent heart attack, but what many people do not know is that aspirin will also help prevent colon, bile duct, breast and other cancers and can improve outcomes for those who are receiving cancer treatment.1, 2

Those at risk for colon cancer and heart disease who are without bleeding risks, and are between the ages of 50 and 59, should take 81 milligram baby aspirin daily after consulting their doctor.3

Adults 60 years and older may be able to take low-dose aspirin, but this must be determined with their doctor.3
