I had Hashimotos when I was 18 years old. I had low thyroid and had trouble swallowing. I also had a lot of itching on the skin over my thyroid gland. I was scanned for cancer and fortunately it wasn't cancer. I still had to have a subtotal thyroidectomy. I have been on Synthroid or Levothyroxine for 37 years. I have my Thyroid levels checked every six months and have my dosage changed frequently. I have also read the Thyroid and Diabetes are linked. I also have Diabetes. My DH has Chronic Lymphatic Leukemia and was told that IT was the cancer to have. I know of others who have had Thyroid cancer and with the right treatment they lived full and healthy lives. Thyroid surgery is easy and has a quick recovery time. Best wishes!
