I don't want to worry you, but I will say I had a lump on my neck for at least 5 years that turned out to be thyroid cancer. It didn't cause pain; thyroid cancer rarely does

Now, the vast majority of thyroid nodules are benign and that is even assuming it is a thyroid nodule which I have no reason to assume. It could be many things and I don't think the lack of pain suggests anything one way or the other. Neither benign or cancerous thyroid nodules are likely to cause pain. I don't know about other forms of cancer that affect the neck as I have not had any experience of them.

I will say if they do suspect thyroid cancer it is likely that their first step will be to do an ultrasound scan. This just means they put gel on your neck and rub something around it to get scans. If that suggests cancer is a possibility, then a biopsy would probably be necessary. But it is possible the scan could indicate no further treatment is necessary.

You really do need to get both things checked out. They probably aren't connected to one another and neither might be anything serious, but even in that case, the doctor will be able to give you some reassurance.

You are likely jumping on a couple of steps before you will be referred for anything likely to involve needles. Just go and see the doctor. If they suggest referring you for tests, you can tell them how you feel about needles and see if there are any alternatives. And that may not even happen.
