Breast cancer risk may increase for women after recent childbirth, study finds
New research led by doctors from the University of North Carolina and the Institute of Cancer Research in London shows women who have babies may have a greater risk for breast cancer, compared to women without children. The study looked at data from nearly 890,000 women of different ages. It found the risk continues for more than two decades after childbirth. Dr. David Agus, director of USC Norris Westside Cancer Center, joins "CBS This Morning" to discuss the findings.
