Women may be more confused than ever about whether they need a mammogram. New breast cancer screening guidelines released last year by the U.S. Preventive Services Task Force recommended getting your first screening at age 50. Yet some advocacy groups disagree with these new recommendations from a government-appointed panel of experts. The American Cancer Society and Susan G. Komen for the Cure still advise getting your first mammogram at age 40. If you’re at normal risk for breast cancer, consult this guide or your physician. Women at high risk—those who have certain known gene mutations or family members with breast cancer— should talk to their doctors about earlier or more frequent screenings.
