Katie, certainly go for the second opinion. I was also stage II but with an unknown primary, and had 2 infected nodes but no extracapsular spread. That seemed to be a large part of the decision by my team of RO and MO not to put me through chemo. As well, since I was
HPV positive they felt that the radiation ought to do the trick, which it did (so far - 3 and a half years out!)
I think you'll find a wide variety of treatments here, and opinions. The best ones for you of course are from your doctors, as they know the specifics of your situation.
Please let us know as you go along. And hang in there!
