Hayden needs to go to cincinnati

Hayden just turned 13, 3 years ago he was unexpectedly diagnosed with a rare cancer know as Langerhans cell histiosytosis (lch). It was first found in his c3 vertibre, Hayden under went a year of chemo, where he relapsed with the cancer attacking his skin, he went thru more treatment, a week before Christmas we found 2 lesions, one that are thru his skull and one thru his hip, we have since started stronger chemo and on Monday 3/6/2017 we found another on his skull, so he has two tumors that are thru his skull and is sitting on the brain and one thru the hip bone. Not much is known about lch because it is so rare, but there is a specialist that wants to see Hayden but would require us to travel from Florida to Ohio. Please help my son see this specialist so we can get answers and possible healing once and for all.
