Hi, Debi.
You should take a look at our
list or
map of treatment centers for places near where you are. Stanford, City of Hope, and UCLA in California or the Mayo Clinic in Phoenix are possible choices.
There was a recent thread about cellularity
here.
DKimmel has given you the right advice: a second opinion is always important and your son's doctor should not discourage you from learning. It sounds like you do understand a lot of the details, but s/he should be able to answer whatever questions you have.
Regards,
Ruth Cuadra
