I have head and neck cancer but stemming from my ear, not tongue. I have had surgery, radiation with chemo, and most recently an Immunotherapy infusion for the last metastasis. The Libtayo infusions totally shrunk my kidney metastasis away during the 2 years I was on it. There were side effects but quite tolerable compared to dying of cancer. I continue to remain clear almost 2 years since stopping the drug. (Knocking on wood.) There are newer targeted therapy and immunotherapies that can have less side effects than some of the other treatments. You need to talk to a head and neck oncologist for the newest alternatives for your treatment. There is also the option of palliative radiation to slow the growth when cure is not an option. Lower dose with fewer side effects.
