Breast cancer is the most commonly diagnosed cancer in women with a lifetime risk of 1 in 8 in the UK. The disease is associated with considerable morbidity and mortality. The UK breast screening program has been in place for almost 30 years and has evolved with improved diagnostic imaging. The overall benefits of the screening program are subject to continued heated debate with multiple potential harms. The aim of this review is to provide the non-breast specialist health-care professional an overview of the evolution of the breast screening program, a summary of the evidence of the benefits, and a description of the harms. In addition, the diagnostic methods currently employed as well as potential future changes to the screening program and imaging techniques will be covered.
