HI there welcome. Your tumor if on your oral tongue may not be HPV related but they should test it if and when they resection it. Try not to worry this is a flukey disease many stage 4s have walked away from their dx with no problem and we've lost some stage ones. The poor prognosis of oral cancer is based on a melting pot of people - A lot of the older and in poorer health. Since in the past OC had a lot to do with poor habits - heavy drinking and smoking, those numbers are skewed - even if you are older, as long as you are in reasonable health and do what has to be done, you should be fine. Ideally oral tongue treatment involves a resection of the tongue and then depending on margins and nodal involvement rads and chemo. The good news is rads has changed a lot, and likely you can have it again. Please do push to be seen at a CCC and most importantly do whatever you can at this point to beat it. Do not tread lightly. throw the book at it if that option is offered. particularly if it's not HPV related. hugs. and welcome.
