Cost of Karinna son's Leukemia treatment

Karinna Harriot's 6 year son Kamden was recently diagnosed with Leukemia (AML) in March. He just had a Haplo bone marrow transplant this past Friday May 6th and Karinna was the half match donor. This was his second transplant and the doctors say that this treatment related to AML and was caused by the first transplant which is extremely rare but he was unlucky and got hit by lightning twice. He will do a clinical trial after the transplant to ensure he stays in remission. Please say a prayer for Kamden that his AML Leukemia doesn't come back and he doesn't get any other cancers ever in his life.
