The doctor called me this afternoon and told me that the cells from the biopsy are NOT cancerous! Praise the Lord! I'm so grateful for the sense of peace that I had for the past week! I realize now that I was holding on to some stress about it since when the doctor said it was benign I let out a huge sigh of relief. He said they will keep an eye on it, see what it does, and do another ultrasound in a year. Meanwhile, I'll be having a sleep study in a few weeks and then discussing with both my primary care doctor and the ENT the idea of increasing my thyroid medication in order to surpress this nodule. We'll see.
