Peggy, I have a family member with lung cancer that has metastasized to his brain, he is 57 years old...he's had radation on brain 2 months ago. Doctors say that now they can only treat symtems, also he has shingles on his head and eye. They gave him 6 moths to live.
It sounds like your son is doing better than thought, I will send this to my family member. Please let me know if there is anything else I can help you with or any news you might get.
God bless you and your son.
Please excuse my spelling...
Sincerly, Lynette
