ONE-VIEW VERSUS 2-VIEW MAMMOGRAPHY SCREENING - A PROSPECTIVE POPULATION-BASED STUDY

In order to compare mammography screening with one versus two views, a prospective population based study was carried out. Mammograms from 1 2 636 women aged 40 to 54 years were examined first as one-view screen ing and later as two-view screening. The initial results showed that t wo-view screening resulted in 349 recalls, 72 surgical biopsies, and 3 2 breast cancers. One view screening resulted in 542 recalls, 61 surgi cal biopsies, and 29 histologically proven breast cancers. The follow- up revealed 2 additional cancers detected by one-view screening. Thus, the use of two-view screening resulted in one more cancer case being detected. The difference in breast cancer detection was not significan t.
