My Mom had AML, a type of leukemia that is aggressive and usually fatal. She was in her early 70s when she had it, back in 2004. Although they didn’t want to tell us openly, the doctors seemed to suggest to us that my mother was doomed. It’s been 7 years since she had it. She defied the doctors. I am so proud of her. We can only hope and pray in such terrible circumstances. Remember, just because someone has a rare form of cancer, or any cancer for that matter, doesn’t mean that it’s an automatic death sentence for him/her. Every person is different, and responds to treatment in a different way, and also reacts to the cancer in a different way. I hope your friend can beat it. Good luck to him.
