title: Current perspectives on indications and limitations of mammography.
abstract: Women have a 7 percent natural lifetime risk of developing breast cancer, which is the leading cause of death in women aged 40 to 50 years. Most data suggest that the earlier the disease is diagnosed, the better the chance for cure. Women with "minimal breast cancer" have an actuarial 20-year survival rate of 93.2 percent. The majority of these breast cancers are diagnosed by mammography. The radiation doses from this technique have been dramatically decreased over the last ten years to about 0.1 to 0.6 rads per study. The two largest breast cancer screening studies, the Health Insurance Plan of Greater New York and the Breast Cancer Detection Demonstration Project, have shown conclusively that women over 50 years old can benefit from annual mammography and that certain groups can benefit from mammography at close intervals before the age of 50 years. This article describes the development of mammography and outlines current perspectives on its indications and limitations.
