The majority of malignant thyroid nodules can be cured after surgery, and most of them are papillary and follicular carcinomas, collectively known as differentiated thyroid cancer. 10-year survival rate can reach over 98% and 20-year survival rate can reach over 90%, so the treatment is very effective. Surgery is only one of the means to treat malignant thyroid nodules. After surgery, medications are usually needed to control the cancer, commonly thyroxine tablets, the main purpose of which is to inhibit the secretion of thyroid stimulating hormone (TSH) and inhibit the growth of thyroid cancer cells. Some patients only have their thyroid cancer tissues removed, but the lymph nodes are not removed. At this time, they can also undergo nuclear therapy, which can kill the remaining thyroid cancer cells through oral medication. There are also some malignant thyroid tumors such as squamous carcinoma, which may require radiotherapy or targeted therapy, but in general thyroid cancer is very curable and can usually be treated very well after surgery.
