What is the test?

In an excisional biopsy of the breast, the surgeon makes an incision in the skin and removes all or part of the abnormal tissue for examination under a microscope. Unlike needle biopsies, a surgical biopsy leaves a visible scar on the breast and sometimes causes a noticeable change in the breast's shape. It's a good idea to discuss the placement and length of the incision with your surgeon beforehand. Also ask your surgeon about scarring and the possibility of changes to your breast shape and size after healing, as well as the choice between local anesthesia and general anesthesia.
