Sammie, yes, go to the UK and get treatment there or at least recommendations about radiation and chemo. fwiw, I am stage II, a smaller tongue tumor than your husbands and no nodes involved and I still got what I consider a reliable and strong rec. to have chemo and radiation after surgery. Another thing I was told is that with a large tongue tumor that is anywhere near the middle of the tongue (sounds like a 6 cm tumor might have to be?) you actually can't be entirely sure about no mets to nodes on the neck unless you have a neck dissection of some sort done on both sides.
