Well I am back at work and trying to get my head around the emails and back log. I just got a call from the Doctors office telling me I have 3 appointments on 2/17/10 with a Dental Oncologist a radiation Oncoligist and a Panerex or some other type of xray. They finally explained that the problem with Perineural invsasion is that while they may have gotten clean margins the cancer Jumps, for lack of a better word, along the nerves and it would be possible to have jumpled beyond the margin. So much for thinking this was behind me.
