Single view mammography: a simple and efficent approach to breast cancer screening.

In 1974 a new approach to breast cancer screening was introduced--the single view mammography method. An urban nonselected population of 6845 women of more than 34 years of age were screened with one roentgenogram of each breast. By this method it has been possible to reduce the radiation dose, while the patient flow is increased and the costs are decreased to an acceptable level. Forty cases of breast carcinoma were detected (6.7/1000). Twenty cases were preclinical.
