Hello Mark
I had 7 weeks of radiation along with 7 weeks of chemo.
Was diagnosed stage 4 floor of mouth. Feeding tube was a blessing. Was eating puree diet by mouth mostly soup and water till about the 20th treatment. After that couldn't get anything in orally for rest of treatment. So I lived on feeding tube. It got even worse after treatment was done. Was a good month after before i was able to start puree diet again. Now im eating solid food again last couple months been much better. Hopeing they remove tube in the next month or so.
If your having problems already you should get the tube installed. Radiation may get alot worse.
Very simple operation. Took about 40 mins to complete. Was a local anesthetic. No pain. More discomfort that anything.
I wish the best of luck to you
Mike
