I had good response from my Chemo and Radiation but my ENT was pretty persistent in the ND as a precautionary measure. As it turned out, the post surgery biopsy showed only on microscopic malignancy in one node. But like someone stated above, it's not without its side effects/ risks. I in some ways feel the surgery was more to recover from than chemo or radiation. I had a bit of numbness all the way to my ear. Now I have a bit of tightness on that side. But like stated, statistically, it makes good sense.
