During a mastectomy, most of the breast nerves are cut and the area becomes numb. Breast reconstruction can restore the appearance and feel of the natural breast to a certain degree to whoever touches it. However, the patient won’t feel much sensation in the treated area when it’s being touched. This part can be hard for most women as breasts are an important erogenous zone.   Fortunately, the nerves have the potential to regrow after some years post-op. Some women experience great sensitivity to touch in the armpit next to the reconstructed breast, which can be a new erogenous zone.
