After much thought throughout the evening, a few internal struggles, I am going to have the biopsy done to find out one way or the other. I don't like not knowing. I discussed with the ear, nose, and throat specialist the procedure and feel it is the appropriate course to take. Since the scans and blood work are inconclusive, the biopsy will answer the one remaining question. It will be done as out-patient surgery, take about 15 minutes, and a few stitches.
