evidence: A systematic review of mammography screening studies in women aged 75 years and over. [...] Relevant outcomes included both the benefits (or surrogate outcomes from which benefits could be inferred) and harms of mammography screening. Such outcomes included: breast cancer mortality; all-cause mortality; incidence of advanced breast cancer (or breast cancer stage distributions); prognostic characteristics of screen-detected breast cancers; evidence on treatment patterns (including data on treatment-related morbidity, such as physical adverse effects of treatment, quality of life measures); false-positive mammography; overdiagnosis; overtreatment; anxiety or adverse impact on quality of life; false positive biopsy or surgery for benign findings, false-negative findings (reported as interval cancer rates).
