Thanks for the reasons to be "normally" scared but NOT paralyzed by FEAR! Yes, I did take ONE Klonipen (like Valium) before a PET scan last week and that helped. I also returned to work 3 weeks post neck and base of tongue surgery at UCLA. I had the one + node removed by incision and the base of tongue tumor removed robotically at the same time. Clear margins and no extracapsular spread from that node. Since I am a PERIODONTIST for 25 years, I know "too much" and have a wide medical network to confuse me even more. PS: HPV+ cancer. It appears to me the treatments are not written in stone for HPV+ as far as radiation+chemo or radiation alone since the main tumors are GONE? One of my surgeons even suggested that, IF the node had been 1cm smaller (was 3.5 cm), he would opt OUT of any post surgery treatment????? Then I see the radiation oncologist and he throws the book at me for chemo-radiation????? Thanks for any input! Mark Cohen in LA
