Screening for Breast Cancer: How Useful Are Clinical Breast Examinations?

In terms of breast cancer detection, CBEs performed very well in the study by [Bobo] et al. For first screen examinations, the detection rate was 6.9 breast cancers per 1000 CBE records (95% confidence interval = 6.6-7.2). Furthermore, the analysis reveals that, contrary to what many believe, CBEs do detect in situ cancers. The reported rates were 3.8 and 1.2 breast cancers per 1000 women, respectively, for invasive and in situ breast cancers. But this is looking at CBE in isolation from mammography.
