In 2016, the U.S. Preventive Services Task Force issued the first-ever recommendations for daily aspirin to prevent colorectal cancer. The guidelines say that people 50 to 59 years old who are at increased risk of heart disease may also gain protection against colorectal cancer by taking a daily low-dose aspirin.
The recent batch of new low-dose aspirin findings doesn’t alter those recommendations, but more research is needed. For now, if your doctor has recommended a daily low-dose aspirin because you’re at increased risk of cardiovascular disease and colorectal cancer, continue to take it as directed. If you’re thinking of taking low-dose aspirin, talk with your doctor before you start.
