While most breast cancers are found in women who are 50 years of age or over, about 1 in 10 diagnosed with breast cancer are under 45, and often their cancer is in a later stage when it’s discovered. On this episode, Nina Vincoff, MD, clears up the confusion around mammogram guidelines. She says every woman should go through a risk assessment at a younger age to determine their risk — something most do not discover until their first mammogram. For those at high risk, this can have deadly consequences. The chief of breast imaging at Northwell Health explains what average risk means, how it is calculated, who is at the highest risk and steps women can take before going to their doctor's office. Chapters
