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.
One study linked multiple pregnancies to an increased risk of developing atrial fibrillation later in life, and another investigated the association between premature delivery and cardiovascular disease.
