Hello Gita, may I suggest DR. Terry Shibuya, he is in LA at UCI Irving. This is my "NEW" doctor and he is absolutly WONDERFUL. I just had a radical nck dissction, removal of 90% of my tongue, lymph nodes on both sides. I also had to have my jaw replaced for the cancer had spread into my jaw bone.This required they take the bone from my leg to rebuild the jaw and a skin graft from the same leg for the flap inside the mouth where the floor and tonue used to be. This my third fight with "C" Cancer. This was my last hope, without the surgery I would have only had 3 months. He and his team have done a wonderful job with me..My only regret, I didn't have him the first time I got "C" Cancer in 1989.. I would not be in the shape I am in, I honestly believe this. I am so so sorry to hear all this about your sister, she has been thru so much already, God Bless her and her family. Vicki
