Hello Ingrid. My sister had the same surgery 6/2/10. Had 30 rads and 3 Erbitux(stopped because of rash). Welcome to OCF. You have come to the best place for answers and support.
As for now eat everything and anything you can before rads. You need the weight and it's going to be hard to eat for alittle while.
Glad to hear there wasn't any node involvement. My sister was lucky with that also.

CG to Sister (42). Smoker quit @ diagnosis Dx 4/20/10 SCC T2N0M0, Rside of tongue Hemigloss R neck dis, all nodes removed 6/2/10, Trach and NG in, home 6/8/10,8/18/2010 start erbitux x6, 30 IMRT end 10/11/10 with only 3x erbitux due to reaction and one week off of rads
