Dear Jean, here's another opinion from a very opinionated caregiver Rad. treatments can be really tough. PEG tubes can be a lifesaver to an oral cancer patient. Caregiving could be really hard, depending on the reaction of the patient to the rad tx. You all need to ask lots of questions and be prepared for any eventuality during the next months. [the effects of radiation can last months longer than the tx dates]. PD is one thing, oral cancer is a different thing. Just try to be prepared for what you can. Amy in the Ozarks
