Mark!
Welcome to OCF brotha Congrats on getting through rads!
HPV tumors respond very well to radiation and have a better prognosis (generally) then
HPV- so you Dr is correct!
Anxiety comes with the territory with this disease and the emotional scars can take longer then any physical damage when it comes to cancer. Give it time and plug into these forums to get support. Always be diligent going forward but you're alive so celebrate that brotha.
Ive detailed my journey to emotional healing in my blog on the Coping Anger/Fear section called Letting the Healing Begin, check it out and maybe you can relate to some of the realizations that helped me through.
Welcome aboard my friend
