Hi Palermo, am new to this forum after having a full thyroidectomy this March following a diagnosis for thyroid cancer (that had already spread to the adjoining lymph nodes). The whole started with a swelling on the right side and difficulties swallowing. When I went to see an Endo then, all tests (incl. FNA = fine needle aspiration) did not show anything serious/malicous but he did indicate that 'should the symptoms persist, or come back, that perhaps I 'should consider having taken half of the thyroid out in a few years as one can perfectly well live with just half'.
Then all turned to somewhat normal, without any visible or major swelling between 2013 - end of 2015. In January this year the same problem started again, with more difficulties swallowing and affected breathing as well (sort of a wheezing noise, mostly when lying in bed). More tests of the same kind and in fact my endo (a different one) now said I should not delay to have half taken out a) to ensure that I could swallow and breathe better/normally as it was pressing a bit on the windpipe and b) so that they could do further tests on the part they took out.....end of story is that after that first surgery in March they discovered cancer. And not an encapsulated type (so not like a single tumor surrounded by tissue) but cancerous cells dotted on/around the thyroid. So second surgery to remove the remainder of the thyroid and adjoining nodes followed within 2 weeks of the first. Then after some rest and healing period, I had RAI (radio active iodine) which is less invasive than chemo but still obviously not a walk in the park for your body. I returned to work in May, after two months off.
It's not my intention to scare you but to make you aware that I would not underestimate or brush off things, but rather go and do all possible tests you are being offered. It might turn out nothing and go away, but then it might not or return. Better safe than sorry! Given that my FNA (the needle test) came back 'unclear'...I think this was my and the doctur's cue to 'dig' deeper. Am glad it's out and my neck turned to a normal one with a barely visible scar, and I am on my new current battle to find a doctor that gets me off the synthetic Levothyroxine and on the NDT (natural dessicated thyroid) instead. Wishing you all the best and that your tests turn out normal.
Oh, I meant to add for everyone else here, if you know of such doctor (private or NHS) here in London who considers NDT as a form of treatment, please pm me.
