Doctors say women with aytpia or DCIS should seek second opinions after breast biopsies

The accuracy of breast biopsy diagnoses has not been well studied, but it is a critical element in treating women with breast disease appropriately. This work takes a new approach to informing what is known about the over- and under-interpretation for breast cancer and benign breast disease, and identifies the greatest clinical challenge for accurate interpretation. This study involved 115 participating pathologists from 8 states, providing a total of 6,900 breast pathology interpretations. The overall concordance rate was 75.3%, with a rate of 96% for biopsies with invasive carcinoma. The concordance rate for atypia was just 48%, and it was 84% for DCIS. Read more here.
