I have no idea if there is a link but most forms of thyroid cancer are pretty mild. I had thyroid cancer two years ago. I had my thyroid removed and really no more trouble. I was out of work for a month, recovering from the operation. It probably wasn't any worse a situation than having something like my appendix removed.

I did have to have radioiodine treatment afterwards to reduces e the risk of recurrence but that was really just a couple e of swallowing a capsule. It's a once off too. And now I take tablets to replace what my thyroid used to do.

But my life hasn't changed in the least. I am just as fit and healthy as before and really was for all except a couple of weeks after the operation. And even that was just a matter of getting tired a bit earlier than usual and my neck being sore. By the time I went back to work, the worst thing was my voice was a bit weak.

I am totally fine and so far have no sign of recurrence. 

Yeah, you really are going through it. But the odds are still probably against its being cancer.

And even if it is, it is likely to be a very different scenario to what you have experienced prevously. Obviously, nobody wants any form of cancer, but there are a lot of comments online about how if you had to have cancer but could choose which type, thyroid cancer would be the one to choose.

And for full disclosure's sake, my nodule was 10.5cm and the cancerous part was 6.7cm and there was spread to the lypmh nodes (though only to 8), so even if you do have thyroid cancer, it is likely to be smaller and less concerning than mine.
