Hi benjomax, I would like to say welcome but although there are some great people here it's not the sort of group/forum that you look forward in joining. It sounds like we have had a similar cancer, mine was also on the right vocal chord.I was diagnosed in March 05 and had radiation end April/May 05. Even though I was already speaking with a hoarse voice before treatment, during it, it got worse and lost it for at least another 2 months after treatment although it did get better day by day so I don't think that's anything to worry about, just takes time for the inside which is more sensitive, to heal. As for the swelling I had nothing like you but I did have swelling at the front of my neck that felt like something was being tied tight around my throat yet nothing was there, my ENT doc said it was lymphedema and just to massage my neck whenever I was sat doing nothing and that would disperse the fluid, luckily that worked over time but I still get swelling occasionally but I do what he suggested and it goes away again.
Where in the UK are you?. I'm in the Hull area and have only had one CT and Biopsy in all the time I've had this and both where before treatment nothing since only regular check ups once a month for the first year which have now changed to 2 monthly. I'm pleased that your docs are keeping an eye on you and if it helps please go to my cancer site where I tried to keep a diary of all that happened to me the link is below. By the way I'm 50, never smoked in my life and don't drink.
