Doctors advise early breast cancer detection in wake of Edwards' death

Following the passing of Elizabeth Edwards, who died Tuesday from breast cancer that spread to her liver, doctors are highlighting the importance of early detection of breast cancer.

Today on American Morning, Dr. Freya Schnabel, director of breast surgery, NYU Langone Medical Center, says early detection "remains our greatest weapon against breast cancer." She explains the important steps women can take, what role mammograms and MRIs play, and how often women in their 20s, 30s, 40s, and beyond should have clinical breast exams.
