Chock I agree with AnaD. She should definitely be considered for radiation. I was a T2N1MO and they threw the book at me... I caught it and ran with it... I was grateful they recommended it. Is she at a CCC? I had a friend recently who had a similar DX he was a T2N0M0 - the dr. said we got it all go home. He went to florida - 2 months later a node popped up and then he was in trouble. He returned home they sent him for some half assed rads treatment with no chemo - it was broken up for some odd reason - nothing like I had ever seen. I mean it was the proper rads but they gave him two weeks on two weeks off, and no chemo which was bizarre. Anyway his funeral was last week.
My point is - this cancer can be highly aggressive. It should be treated aggressively. There are certain things they look for that indicate further treatment - ece (extracapular extension) Peri neural involvement - tumor was large enough to touch a nerve (a lot of T2 tumors have this factor). I would ask more questions and if she's not at a cancer center get her there for a second opinion.
hugs and best of luck.
