title: Twenty-year follow-up of minimal breast cancer from the Breast Cancer Detection Demonstration Project.
abstract: Since the 1960s, the potential benefits of early detection of breast cancer through screening with physical examination and mammography have been studied. In a mass screening study begun in 1973 by the Breast Cancer Detection Demonstration Project (BCDDP), mammography detected 90% of the cancers that were diagnosed. Of the women aged 35 to 74 years from the BCDDP study who were diagnosed with minimal breast cancer, the 20-year cumulative breast cancer survival rates were 95.8% for 469 women with in situ breast cancer and 82.8% for 769 women with invasive breast cancers 1 cm or smaller in size.
