Women between the ages of 50 and 79 would benefit from yearly mammograms and, by having these mammograms, reduce death rates from breast cancer by 37%. Researchers observed benefits for women in this age group who were tested every 2 years. The researchers reached their conclusion using a statistical calculator based on various studies of breast cancer and mammograms.
Marvin Zelen, PhD, who developed the statistical tool with a colleague, said that the model was not meant to give an absolute guide to whether more screening is wise.
Instead, the researchers would like to develop their program into a Web site.
This Web site would allow women to calculate their own risk and determine when to have mammograms.
