The Health Insurance Plan of Greater New York (HIP) Breast Cancer Screening Trial was a randomized screening study designed to test if breast cancer mortality rates could be reduced through the use of periodic screening. Periodic screening was composed of an initial examination followed by 3 subsequent annual exams. Screening consisted of a clinical breast examination and mammography. The study concluded that periodic screening resulted in a reduced breast cancer mortality rate. The effect appeared to be concentrated in participants over the age of 50.
