I am not a nurse but I did have thyroid cancer and can reassure you on a number of levels. Firstly, as I kept chanting to myself when I was awaiting the biopsy and then its results, "thyroid nodules are common; thyroid cancer is rare." Only about 5% of nodules are cancerous, so the odds are very high this is not cancer.

And even if it is, thyroid cancer is not like breast cancer. You won't be getting chemo or radiotherapy or any ongoing treatment. If it is cancer (and it's probably not), they will remove your thyroid and maybe some lymph nodes and then you might have to have radio-iodine treatment afterwards, which is basically just swallowing a capsule and doesn't usually have any effects at all, although you do have to be in isolation for a while afterwards as you are radioactive. 

As regards what to expect, you should get the results of the biopsy within a week or two. Most likely, they will tell you it is benign and that will be the end of it. It's also possible it will be indeterminate, in which case, you will have to have another biopsy or have half your thyroid removed so they can test it. 

The least likely option is that they will find malignancies, in which case, they will remove your full thyroid and possibly some lymph nodes. In my case, I had my operation on the 6th of January 2020. I was in hospital just under a week, then was off work for a further three and a half weeks. My voice was a bit weak for maybe two months after the operation (as you can see from the date, the world shut down after that, so it's hard to tell how long it lasted because I wasn't spending much time in loud environments where I would need to raise my voice from March onwards!!) and I couldn't carry anything too heavy in my left arm for about 6 weeks after the operation, but otherwise, I was fine after a week or so.

I do have to take medication now to replace my thyroid, but that is just taking two tablets each morning.

I had radio-iodine treatment the following May which was annoying due to the whole isolation thing, but otherwise, no big deal. I had a nosebleed 10 or 11 days after the treatment, but that was the only effect it had on me.

My nodule, by the way, was 10.5cm, so more like the size of a hockey ball than an olive.

Thank you for your reply. I am hoping it’s not cancer but with them wanting to get the biopsy done quickly they are obviously concerned. 
Does the biopsy hurt ? 

I don't think their wanting to get the biopsy done quickly means they are particularly concerned. From what I have read, two weeks is the norm in the UK whenever there is any possibility of cancer. That seems to be a standard thing and doesn't indicate anything one way or the other.

And the biopsy felt kinda like when you prick your finger on a needle while sewing. Stings a bit but that's all.

Best of luck. I hope it turns out to be completely benign.
