dos-Santos-Silva I, et al. - Authors assessed if current strategies for early detection of breast cancer, including clinical breast examinations and mammographic screening, have caused a decline in the prevalence of late-stage breast cancer at diagnosis. Females aged 18–89 years (n=247,719) diagnosed with invasive breast cancer in Brazil were included in the study. Late-stage breast cancer prevalence at diagnosis stayed high from 2001–2014, at around 40%, and was inversely correlated with educational level; it was also higher for women who identified as black and brown vs those who identified as white. Late-stage breast cancer at diagnosis was highly prevalent across all ethnoracial and social categories in Brazil which means that early detection policies might have had a minor effect at best on breast cancer mortality. A timely diagnosis of symptomatic breast cancer should be the priority vs screening for asymptomatic disease.
