Age 50 as Mammography Screening Threshold Proven Unfounded

The landmark breast cancer screening study of women 40-49, published online in Cancer, has proven annual mammography screening of women in their 40s reduces the breast cancer death rate in these women by nearly 30%. The results of the largest study ever conducted on women in this age group confirm the use of the age of 50 as a threshold for breast cancer screening is scientifically unfounded. Women should begin getting annual mammograms at age 40.
