WZ, all the cancer was on the left side only at one point, tongue, lymph nodes, etc. I think they wanted to leave the right side alone for just this reason. IF need be, they can still irradiate the right side. (I had IMRT, one of the benifits)

The oncologist said PET was only 67 percent accurate, not high in my opionion, that's why they're only doing needle biopsy. I suspect this is going to lead to surgery to remove the node anyway. Had a scan last month, there was no change from last month to this month in size, shape, etc of the suspicious node. But, it was easily identifiable on the CT this time, not so easily identifiable last time.
