Breast cancer: evaluating mammography in early diagnosis

The high incidence of breast cancer among American women has made early diagnosis the focus of large scale research efforts. X-ray mammography plays a key role in achieving the goal of early diagnosis inasmuch as mammography is currently the best proven imaging modality for the diagnosis of breast cancer. Data demonstrating the efficacy and safety of mammography are summarized and radiographic features of breast cancer are outlined. Newer, more invasive methods used in conjunction with mammography are also discussed. It is hoped that the emphasis on practical considerations will enhance the understanding of the primary physician caring for women in order to increase the current under-utilization of mammography.
