Efudex treatment for graft site. I had Mohs surgery 3 months ago above my right eye for BCC with a skin graft the size of a silver dollar from a donor site on my chest. I also just had a Mohs on my nose for BCC and squam with a flap repair from between my eyes. I will need to use efudex on my face soon. Is it safe to use the efudex on the graft tissue and on the flap repair? Thanks
