What is the medical term meaning surgical incision into a breast?

The medical term for a surgical incision into a breast is "mastectomy" when referring to the removal of breast tissue, but if specifically focusing on incision without removal, the term "breast incision" or "incision of the breast" may be used. The term "incisional biopsy" is also applicable when the incision is made to obtain tissue for examination. These terms can vary based on the context and purpose of the procedure.
