The U.S. Preventive Services Task Force (USPSTF) has issued updated guidelines for breast cancer screening, recommending biennial screenings for women starting at age 40. This guidance applies to cisgender women and individuals assigned female at birth between 40-74 years old, excluding those with a personal history of breast cancer, high-risk genetic markers, or a history of high-dose chest radiation therapy at a young age. For these exceptions, individuals should follow their doctor’s personalized recommendations.
