My thoughts are with you at this moment, it is a hard fight. But it is one you can win, a positive outlook is a great help in any healing.
I have been told in a very late phone call this evening (unusual for specialists to call) that the tissue in my Larynx has become Necrotic and no longer truly viable. The answer from a panel of specialists a little earlier in the week look at all the aspects of my prognosis and agreed that removal or maybe at best a partial removal of the Larynx.
Should you come to this point look at all the positives and your longer term survival. You need to keep a watch on your weight and try and keep your strength up. More power to you in this fight, sending my best.
