More than 40,000 women are expected to die this year from breast cancer, according to the American Cancer Society. That’s a staggering number, but death rates from breast cancer have actually been declining since about 1989, and the group says it’s most likely because of earlier detection through screening and increased awareness. The American Cancer Society has issued new guidelines on when many women should get mammograms: at 45, instead of 40. Dr. Carolyn Bruzdzinski, Vice President of the American Cancer Society, and Dr. Sally Friedewald, Division Chief of Breast and Women’s Imaging for Northwestern Medicine explain the new guidelines.
