At their physician’s direction, millions of people take a daily aspirin to prevent heart attack and stroke and help improve blood flow to the heart. Evidence of a daily aspirin’s cardiovascular benefits has been building since research began on the topic in the early 1970s.

Over the years, additional research not only confirmed the benefit of a daily aspirin, but also illuminated other benefits. Research has concluded that aspirin may help prevent a first and second heart attack or stroke. In addition, continuing research has found that aspirin can reduce the risk of certain types of cancer, such as ovarian, colon, pancreatic and esophageal cancers.

Starting a daily aspirin regimen should only be considered after consultation with a physician. Aspirin, like any medication, can cause several side effects and may affect people in different ways, depending on the dosage.
