Breast cancer affects one out of every eight women in the United States. If it hasn't touched your family or friends, it could. This morning, there's new information that many of the women affected might not have needed painful, unnecessary surgery to remove the entirety of a patient's lymph nodes.
American Morning's Kiran Chetry spoke with Dr. Monica Morrow, a surgical oncologist with Memorial Sloan Kettering Cancer Center and the author of this new study in the "Journal of the American Medical Association." Morrow explains why this is good news for women.
