What is the success rate of double incision mastectomy ?

[Gappell]

Hi, My friend is considering a female to male top surgery in a clinic in Mississauga. ( http://www.ftmtopsurgery.ca/ftm-procedu ... astectomy/ ).. She has large hanging breasts. I really have no idea about this. But I really want to support my friend, as she is neglected and teased by her own family. I am researching about this surgery in detail and came across double incision mastectomy. What is the success rate of this surgery? It would be really helpful if someone explained about this. Thank you in advance.
