Dr. Samuel Padua, a radiologist who specializes in breast imaging, explains why a yearly mammogram starting at age 40 is still the foundation of early detection. He also explains why every woman should talk with her doctor about her personal risk starting at age 25. He covers dense breasts and the new rules for reporting breast density, plus other studies that can add to a mammogram, such as ultrasound, MRI and tomosynthesis (3D mammography). He also explains the difference between self-exams and breast awareness. The message is clear: the earlier you start, the simpler the road ahead.
