oral tongue cancers are less likely to be HPV induced?

fwiw, I heard from one rad. oncologist (but he is the suspect one I first went to here who thought I didn't need rad and left suddenly) that he thought in general the cancer became more aggressive as it moved back along the tongue. This was a man with some years experience as an RO at another major center before he came to our neck f the woods so I'm not totally discouting it. I got the distinct impression from him that oral tongue cancer was less aggresive, in general, than BOT. Has anyone else read or headr this?
