The American Cancer Society has updated breast cancer screening guidelines with some significant changes that align more closely with the U.S. Preventative Services Task Force.

Women with an average risk of breast cancer can wait until 45 to start mammograms and then get them once a year.

At 55, women can go to every other year for screening.

These new guidelines join recommendations out recently that change how often women should have pelvic exams and Pap smears.

On Monday morning, Kerri Miller and her guests try to bring clarity to these new evidence-driven guidelines. Dr. Nancy Keating is a primary care physician at Brigham and Women's Hospital in Boston and Dr. Sandhya Pruthi, who specializes in breast cancer research at Mayo Clinic in Rochester, join Miller to sort through the latest research on breast cancer screenings.
