”Papillary thyroid cancer is the most common and the least malignant. It accounts for about half of all thyroid cancers and is most often seen in children or young (before 40 years of age) female patients, some of whom have had neck x-rays as children. The tumor is slow growing and can be confined in the thyroid gland for several years. The lesion can spread from the primary site to other parts of the gland and local lymph nodes via the intra-glandular lymphatics, or can be confined for several years, so it is easy to ignore its nature. Pathology reveals well-differentiated columnar epithelium with papillary protrusions, clear nuclei with eosinophilic cytoplasm, and often concentric gardens of calcium salt deposits. Clinical manifestations are rare except for nodules or local lymph node swelling. On thyroid nuclear scan, the nodules appear as cold nodules; on neck x-ray, the tumor may show fine dotted or concentric calcium deposits. Papillary carcinoma can be stimulated by TSH to grow and shrink with thyroid hormone. If the envelope is intact and there is no metastasis, the life span is normal. If there is vascular invasion, 80% of patients have about 10-year survival rate. “The above is the content of the Baidu library, I copied, the description is accurate, focus on a few points, so that you suffer from this disease patients relief. 1, the majority of early and mid-term life expectancy is normal! 2, thyroxine post-operative treatment is effective, check the T3, T4, eat well eugenol! 3, for patients with larger tumors or later recurrence, total thyroid excision is recommended. 4.No need for radiotherapy.
