According to the American Cancer society

  • over 250,000 new cases of invasive breast cancer will be diagnosed each year in women in 2017 and over 2,400 in men;
  • approximately 40,000 women and 440 men died of breast cancer in 2015;

Currently, the American Cancer Society recommends yearly mammograms for women aged 45-54 for women at average risk for breast cancer and mammograms every two years for women aged 55 and older, who should also have the option to continue yearly screening.
