Welcome to OCF! No question is too basic. You came here for help and we will do our best to assist you. Read both the posts here and also on the main OCF pages (click on the words OCF Main up towards the top left corner).
A second opinion at a CCC is what I would suggest. Waste no time in getting your father to one of the country's top CCCs. Being in Texas, MD Anderson is one of the very best CCCs in the country.
Im not sure why your fathers treatment plan is for palliative care as a first choice. Please understand our group is made up of caregivers and patients/survivors of oral cancer. We are not medical professionals, we lack years of schooling and training, we also do not know the patients background or test results. Which is why we may not be able to always answer your questions. We will always try our very best to help you.
Heres a couple link that may be helpful. Best wishes with everything!
