Katie I had similar surgery to you chemo and rads bilaterally to my neck - my voice has not changed - it took a while to get back to normal but I can still sing... (mucous pain etc) There is someone else on the forum who also has had a similar cancer is cancer free and is a professional vocalist, AnneO is a vocal teacher and she is also doing well. Hugs! And eat up. I was 40 lbs over weight - despite not using th peg I only lost 22 lbs - then post treatment I gave up bread and sugar - lost another 20 - I'm at my perfect weight right now. (the sugar and bread Is a therapeudic omission.)
