New and need some help!

I have read here for a long time and find it very interesting. My neighbor was just sent home to die with cancer in every part of his body except his head and a family member found a dr. in Georgia who had cured a woman here with cancer.
So they called him and he came and sold them some CS, and told him he would fell better in 3 days. Today is the 3rd day and his wife says he is not any better and has slept all day. He is a lovely man, is there any thing to be done for him?
Thank you
