FDA proposes changes to breast cancer screening
The FDA is proposing the first changes to breast cancer screenings in decades. It wants to require mammogram providers to notify women about their breast tissue density. About half of women over age 40 have dense breasts, which can obscure cancer signs. It is also an additional risk factor for breast cancer, which is the leading cancer among women. Dr. Tara Narula joins "CBS This Morning" to discuss the changes.
