Overview

The article of professor A. B. Miller and colleagues published in February 2014 in the BMJ, which summarizes findings from 25 year follow-up in the Canadian National Breast Screening Study made in the first half of 1980s, doesn't bring new compelling evidence of the ineffectiveness of mammography screening and its conclusions are similar to the previous article about this study published in 2000. Several recent reviews have confirmed a reduction in mortality from breast cancer by tens of percent due to mammography screening. Different results of this study might be due to specific design of the study and used mammographic techniques. It should also be noted that results extrapolation from long-term foreign studies in terms of other country must be done very carefully.

Key words:
Canadian National Breast Screening Study – mammography – screening
