Sorry to hear your worrying tabi. I know the feeling all to well. I am a bit better now however, though this mucus things is annoying me still. I feel more relaxed. I still have another appointment with the fourth ENT. While I feel it is probably nothing serious it doesn't mean I'm going to give up chasing it. I have symptoms so that means there is a cause. Just because it may not be treatable does not mean I should not know what it is. That is the same advice I would give anyone.

Your results are very encouraging however. Could you ask for the biopsy to be tested for HPV. I'm don't work in a path lab or anything but I'm sure biopsies are kept on record for future tests if needed. You could ask about that.

Also, with removing the lesion I think the ENT has said this because it might cause more issues that you already have. My reading found BOT surgery can create issues particularly with swallowing and speech.
