Obviously Dr. Fischer is a very busy surgeon.. I'm currently dealing w/a melanoma that was removed from my nose and Dr. Fischer will remove a lymph node at the same time the Plastic Surgeon goes to repair my face after the skin-flap surgery.. Because of their conflicting schedules, I'm still waiting to hear when this will happen.. Dr. Fischer seems like a very caring individual and I'm hoping the necessary procedures can take place soon.
