Nearly had a personal experience with this. A very dear friend of mine was scheduled to get a thyroid biopsy in late March 2020. When the coof arrived, it got cancelled and she didn't actually get the biopsy done until it was, I think, October 2020. Now, in her case, it came back negative but if it had been positive then I shudder to think how much more dangerous an extra 6 months of thyroid cancer growing and spreading would have been, just because of unnecessary panic.
