Mammography examinations reduce breast cancer mortality rate: SCRY Study

August 04, 2017

A comparison between the group that underwent mammography and the control group that was undertaken for a period before screening started uncovered no statistically significant difference in breast cancer mortality. Breast cancer care in Sweden has moreover been further standardized since that time, not least as a result of care programs and national guidelines. This indicates that the difference in breast cancer mortality is a result of access to mammography screening among 40-49-year-olds.

There is a consensus today that mammography screening for the 50-69-year age group reduces breast cancer mortality. Calling in women aged 40-49 years for mammography screening, on the other hand, has been controversial and much debated since the 1980s, when mammography screening began. Few studies have been able to show any significant effect on mortality in the age group. At the same time, few studies have been designed to study the age group in particular. The Swedish National Board of Health and Welfare recommends screening for the entire age interval of 40-74 years, whereas EU guidelines do not include 40-49-year-olds in their recommendations. In the U.S., the U.S. Preventive Services Task Force (USPSTF) recently changed its recommendations not to include the 40-49 age group.
