Papillary carcinoma, known as papillary thyroid cancer, is treated in the following ways: 1. Surgery is performed to remove the papillary part of the thyroid gland, which can directly remove the diseased part of the thyroid gland to avoid affecting other good parts, while the tumor factor cannot be completely removed. 2. The treatment is to stimulate the release of thyroid hormones in human body by taking thyroid hormone drugs to increase the level of content in human body, which can have the effect of inhibiting the growth of tumor factor and can destroy the growth environment of tumor factor. 3. Chemotherapy, which is the most common treatment for cancer, has certain side effects on human body itself and needs to be considered carefully.
