What is double incision mastectomy? Jan 3, 2016 22:49:27 GMT -8 Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by wismaspings1974 on Jan 3, 2016 22:49:27 GMT -8 Hi.. My friend is considering a double incision mastectomy. Since it is not a common surgical procedure, I have no idea about this surgery. It would be really helpful if someone could explain about this surgery. Awaiting your responses.
