Hi @thetwoofus, I'd like to add my welcome to @merpreb's. I'd also like to bring in a few additional members into this discussion, like @burrkay, whose wife also has lung cancer and @cindylb whose husband has a tumor of unknown primary being treated as lung cancer.

TheTwoOfUS, aka George, you are asking the right questions that you should discuss with your wife's cancer team. Ask how they will take into account her weight and age. These are factors that are considered carefully. But I would want to hear it from her team who know her entire medical history. Her treatments will also be monitored closely to see if chemo and/or radiation dosages need to be adjusted along the way.

Here are the results of a search on US News which ranks hospitals across the nation.

You might inquire if an appointment at Mayo Clinic is possible with your insurance. There may be accommodations available to you if her situation requires expertise that your state doesn't have. You can call Mayo Clinic's Insurance & Billing department to inquire: https://www.mayoclinic.org/patient-visitor-guide/billing-insurance/contact-us

This must be all so scary with all the unknowns. Are they treating the cancer on her carotid artery as a head & neck cancer or as a metastasis of the lung cancer? If you're not sure, that would be a good question to ask.
