Pathologists are concerned about the number of false positive breast biopsies. Which aspect of the testing methods are they concerned about?

The concern of pathologists regarding the number of false positive breast biopsies relates to specificity in the testing methods. Specificity measures the ability of a test to correctly identify those without the disease (true negatives). In the context of breast biopsies, a high specificity means that fewer healthy individuals are incorrectly identified as having breast cancer when they do not.

When pathologists encounter a high rate of false positives, it indicates that the testing method is incorrectly diagnosing individuals who do not have the disease, which reflects low specificity. A focus on improving specificity would mean enhancing the test's ability to accurately distinguish positive cases from negative ones, thus reducing the occurrence of false positives. This improvement is crucial in ensuring that patients are properly diagnosed, avoiding unnecessary emotional distress and potentially invasive procedures stemming from inaccurate test results.
