Breast Cancer Awareness Month: when to start getting mammograms

October is Breast Cancer Awareness Month, and one of the most common questions is simple: when should I start getting mammograms? The U.S. Preventive Services Task Force recommends screening mammograms every two years for women ages 40 to 74.

That starting age is newer than many people realize. In April 2024, the task force changed its guidance. It used to suggest that women in their 40s make an individual decision and recommended routine screening starting at 50. Now it recommends that all women start at 40. For women 75 and older, it says there is not enough evidence to make a recommendation either way.

Not every organization uses the same schedule. Some health groups advise screening every year starting at 40 for people at average risk, as a University of Washington guide for this month notes. People with a strong family history or other risk factors may be advised to start earlier or have additional tests. That is a conversation to have with your doctor, who knows your history.

The same guide suggests three everyday steps: know your risk by learning your family history, know what is normal for your body so you notice changes, and keep up healthy habits like staying active and limiting alcohol.

If you are 40 or older and are not sure when your last mammogram was, check your patient portal today and send a message to schedule one if you are due.
