I don't know enough to suggest anything. I had an ultrasound and then went right to the surgeon and had the surgery. I had multiple nodules and they said I had them for a long time. My vocal chord was damaged during surgery, which is common and I can't sing much and don't speak well, but I never shut up. A year later they put me on a certain diet, took away the Synthroid for a month, and did some tests with a big machine, and said I was free of cancer anywhere. But I am expecting cancer again before I die. That is why I eat so well and study what I can find to read. Please call and annoy the doctors until you get in for more evaluation. Dorisena
