This study was done because the lesion was palpable. The patient had very little breast tissue and mammography was of limited value as it often is if there is a large prosthesis volume relative to breast tissue volume.

The biopsy was tricky. You had to puncture a long way off so as to slide the needle parallel to the prosthesis so as not to puncture the prosthesis when firing the gun.

Core biopsy confirmed invasive ductal carcinoma.
