Final update: The important things
After it was said and done; after all the tension and fear, I am happy to report that it was not technically cancer in my sisters thyroid. She is home, she is out of danger and doing just fine.
What I mean by technically, is there were benign, or what you could call "pre-cancer," cells in her thyroid. If these cells had gone unchecked for a little while longer, chances are it would have developed into actual cancer; but they were caught early enough and in time to pose no further danger to her.
I, again, want to thank everyone who passed along well wishes to my sister and my family. It speaks volumes to what good friends I have, and it is absolutely appreciated.
