Kathleen -
Welcome. No you are not alone with your cancer struggles.
My story is somewhat similar to yours. Radical neck dissection, chemo, hemi-glossectomy, two rounds of radiation 17 years apart, 5 different surgeries on my neck and tongue. Now dealing with limited jaw mobility and using a pump for nutrition.
I can tell you that between my first diagnosis to the recurrence several advances were made in surgical technics and radiation treatments. So, extrapolating the 34 years mentioned in your message, the changes would be almost impossible to describe.
I do think that the advances and options available to newly diagnosed patients are based on lessons learned from early successes such as yourself.
So, again WELCOME!
Enjoy each day for what it is and can offer.
