I am 3 months out of treatment (28 rads then Brachytherapy). I had a CT Scan last week and they reported a stable node on my lung, however that node was not seen on the prior scan. I'm not losing any sleep over that. I was never plagued with mouth sores but yesterday and today, the roof of my mouth is sore. I see my ENT tomorrow so I guess I'll see then if it is anything to worry about. Taking one day at a time. Hope John is on a pathway to feeling better and healing. BTW, a friend of mine, same treatment, had problems with sores and continues to have them 1 year post treatment but, as you know, we are all different in our symptoms and after affects.
