Overall...there is improvement noted and his overall health is in the category of "getting better"
More later...on the phone as I type this.
UPDATE: Off the phone now....my mom did make further mention that the doctor is very encouraged by the PET scan. I am excited to know that the chemo is fixing him and I'm exhausted after waiting around an entire Norwegian day worrying about this phone call. If I could afford a beer I would go have one.
