I had a PEG tube put in two weeks into treatment. I weighed in at about 113 lbs before treatment, so I was not given the option of not having a tube, it was not up for debate. It turns out that I did not need to use the tube, but everyone reacts differently to treatment. I certainly did not like the tube, and I think I had a harder time with PEG than I did with treatment. That being said, if I had needed the PEG, I am sure it would have saved my life.
I didn't lose my voice during treatment. I sang everyday during treatment(at my caregiver's request) and I have no idea if that had any bearing on keeping things working in the vocal area.
I did not work during treatment because I moved to be closer to my Cancer Center, but I was certainly up and about everyday and never took naps.
