A: Combined mastectomy and breast reconstruction is possible
This is similar to the idea of "immediate vs. delayed breast reconstruction."
The combined procedure is possible, and often times, the preferred method of breast reconstruction. This "immediate" reconstruction allows for the best aesthetic result because the skin of the breast is saved and an implant or "self tissue" (DIEP, TRAM, etc) can be placed inside the original breast pocket. The general surgeon and plastic surgeon work together with the first surgeon removing the breast tissue and the second surgeon reconstructing the breast in a single stage. This is the key advantage. The disadvantage can be wound issues from thin mastectomy flaps and/or unresolved oncologic issues at the time of reconstruction.
