Cancer is cancer. Doesn't matter what causes it. Cancers follow the same path - PROGRESSION if you decline conventional treatment. Having an HPV +ve tumour just turns the odds in your favour as they respond much more readily to the conventional treatment of chemotherapy combined with radiotherapy.
Why are you waiting and allowing this to grow more with each day along with the likelihood of metastasizing elsewhere so reducing your chances of cure.
Do you actually hear what is being told to you?
Stop procrastinating. Get to a CCC / your chief Doc ASAP.
Is your family aware of what is happening to you Bill. If you were mine I would give you no choice and just march to medical help.
That is your only chance.
