Hi Whitenoiseb4,
Like you, I had part of my tongue removed 2 1/2 years ago and had no risk factors either. Mine was also a non-healing sore on the lateral border of my tongue. However, I did not have radiation or chemo. So far the studies have shown, tumors on the mobile tongue have not been found to be
HPV+.
Keep checking back here and you will be able to get answers to most of your questions. As you can see already, there are many knowledgable people here that have traveled the road you are going to begin and they are a group of wonderful, caring and sharing people.
Good luck.
Jerry
