I had thyroid cancer five years ago and honestly, while nobody wants any form of cancer, thryoid cancer is really not life threatening in most cases. At your age, it has a survival rate of something like over 99%. And your nodule is tiny, if it's only 6mm. Mine was 10.6CM. So nearly 20 times the size. I think the odds of anything under 1cm being serious are even lower, to the point I've seen things online about how they should change the name so as not to scare people.

The worst that is likely to happen is that if they take out the rest of your thyroid, there is a chance that it could take a while to get the medication right and you could feel tired or out-of-sorts for a while, as they are adjusting things and even that has the odds against it. I've read that happens to maybe 15% of people. In my case, I never noticed any difference at all and I think that is the most usual scenario.

Hi there, had a thyroidecttomy half taken out.   Got another 3 wks to wait, to find out further information.   I am finding this very stressful.  It has been suggested 15 percent to 30 percent was cancerous.   I have been informed that I may have to return to hospital for the other half to be removed, pending results.

It was a Lev3, has been for 2 years, was told cells have now changed.  I have no smell, or taste and have not had for a long while.   Is this normal/

Look forward to hearing from yourselves.  

I have never heard of no smell or taste being related to a thyroidectomy or thyroid cancer or benign thyroid nodules. My initial guess would be that that is unconnected with your thyroid. From what you have said, I don't see any reason to connect the two things. Covid can cause loss of taste and smell and so can other things. Do you have a reason to think it might be connected to the thyroidectomy?

Yeah, if it turns out to be cancer, they will probably remove the other half. But it sounds like there is a 70%-85% chance that won't happen. And if it does, well, it's likely to be pretty much the same thing as you already had with the first half. Not trying to play it down. Two operations would definitely not be pleasant, but at least you know more or less what it is like.
