That's the one reason shying away from neck dissections can be scary - stuff like this should be judged on a case by case scenario rather than just slapping standard practice into play. There's always that 1 in 100 that presents as unusual. So glad they removed a lot of nodes, and yes chemo and rads is par for the course. Sorry it was so involved but since the virus does respond well to this form of treatment and since you had surgery therefore - less cancer is now present, therefore hopefully if there are any stragglers left over rads and chemo will do its job well. Hugs!
