Russ, while you are probably aware of this, I just want to be sure that you discuss this with your doctors. Radiation treatments, even the lower dose IMRT, will beat up your immune system to some extent. That has consequences for your other medical issues. Obviously you are on some meds for you HIV and you've been able to stay ahead of that for a decade. Please be sure that the doctors that who are treating you for this oral cancer are well interfaced with those treating/monitoring you for the HIV. You have unique issues medically, that must be considered by both types of physicians.
