National Mammography Day is observed annually on the third Friday in October as part of National Breast Cancer Awareness Month.

This day serves as a reminder to all women that the best defense is early detection. A mammogram can often detect a problem before there is any outward physical sign. Make sure you get your regular checkups.

HOW TO OBSERVE

Set up a mammogram and use #NationalMammographyDay to post on social media.

HISTORY

President Bill Clinton proclaimed this National Day in 1993.
