There has to be some kind if scar tissue removal..I mean they do it other places.... to me I refuse to have a permanent threachea..I lett them put one in for treatments and a feeding tube I had stage 4 my radiation was 15 minutes for 48 days and chemo 12 :45 mins long every 5 days for 4 months ... I feel like crap 3/4 of the time ... but, apparently the doctors says I don't feel that bad .. I can't figure how they know how we feel when they didn't go through it. But, everything had to come out if I wasn't cancer free .. said I will only go through it once.
