Progress in screening for early breast cancer

Ten years have now passed since the American Cancer Society/National Cancer Institute sponsored Breast Cancer Detection Demonstration Projects (BCDDP) started to evaluate the use of mammography, physical examination, thermography, and breast self-examination in screening women for the presence of unsuspected breast cancer. Criteria have been developed to evaluate population screening as an approach to cancer control and breast cancer screening techniques. Combined physical examination and mammography have been particularly successful in detecting early breast cancer. Although the number of screening programs for breast cancer has increased in the past decade, real progress has been surprisingly slow and the issues in breast cancer screening have proved to be subtle and complex.
