Case Discussion

The value of using previous studies for comparison. It is quite exceptional to be able to biopsy a 4 mm lesion. Review what "overdiagnosis" is. Reading of screening studies should be done in isolated reading areas. If your reading environment is a generally busy, noisy area with distractions and phone calls, you will miss these lesions.

Confirmed lobular carcinoma.
