Thanks dragonfly. ... we have been doing this for three years with him. He has a rare type of cancer. ... only 3 men in the states of Texas has been diagnosed with it. He participates in an experimental chemo program in Dallas. There is no other option for him. When we gets a "fever of unkown origin" they admit him because he had no natural defense against infection. A mild infection can kill him so they are very cautious.
