Breast Cancer Screening: Beyond Mortality

J Breast Imaging. 2019 Sep 4;1(3):161-165. doi: 10.1093/jbi/wbz038.

Abstract

Traditionally, the effectiveness of breast cancer screening has been measured in terms of reducing the number of deaths attributable to breast cancer. Other metrics such as the number of life-years or quality-adjusted life-years gained through screening may be more relevant and certainly may better reflect the important burden of the disease on younger women, their families, and society. The effects of earlier detection of breast cancer in reducing morbidities associated with treatment have often also been neglected. In addition, the harms and limitations associated with cancer screening have been poorly quantified and are seldom put into perspective vis-à-vis the benefits. Here, these alternative measures will be discussed and quantified.

Keywords: QALYs; benefits and harms; breast cancer; life-years; morbidity; screening mammography.
