Question: Is the nodule cancerous? Since you asked, I will say what I saw with my husband, but I really don't want to bring it up. He was dying and your symptoms are what he went through during the six weeks he was in Hospice from his cancer. He also had untreated diabetes and an eating disorder.
My daughter's father-in-law had cancer and lost 40 pounds while his doctor was "just watching it". They couldn't save him by the time he finally was hospitalized. He was only 55 and had colon cancer which has a high success rate with surgery these days. I suggest you get moving on the thyroid nodule and find out more. I survived breast cancer because it was stage one and I ate so well. The first doctor misdiagnosed me. Dorisena
