The First Lady marking National Mammography Day tomorrow at the University of Miami Sylvester Comprehensive Cancer Center in Ft. Lauderdale. Jill Biden is hosting an event with Congresswoman Debbie Wasserman Schultz -a breast cancer survivor herself-who was diagnosed in 2007 and underwent a double mastectomy, reconstruction and several other major surgeries. She says testing is key especially for women under 45. Biden will be speaking about the administration's Cancer Moonshot initiative seeking to cut the death rate from cancer by at least 50 percent over the next 25 years.
