Regulating radiology: ethical issues in mammography and federal legislation.

One in nine women can expect to develop breast cancer over the course of a lifetime, which suggests that a posture of vigilance is appropriate. The form of breast imaging known as mammography will detect masses that self-examination and yearly clinical examinations may miss. Given that most types of breast cancer are not clinically preventable, early detection of such masses offers the best opportunity for survival for the affected women.
