I had tongue and lymph node cancer. SSC HPV with neck disection and reconstruction. 38 radiation and 7 cisplatin chemo. I know most patients don't want the PEG tube but I loved mine. I kept my nutrition up at optimum level. My mouth, tongue and throat had a break . I got the tube after my surgery and just as I started chemo and radiation. I could eat and drink whatever I wanted. I drank a lot of water. I never had to use either of the magic mouthwashes. Just the baking soda rinse often. If you are having pain and unable to keep up with your nutrition I recommend a tube.
