甲状腺肿瘤是较常见的内分泌腺肿瘤,在总人群中的发生率为4%～7%,其中大部分为良性,但约有5%为恶性,即各种甲状腺癌。肿瘤的形成中各种原因造成促进细胞增殖和转化的蛋白表达增多、功能增强。或抑制细胞增殖和转化的蛋白表达减少、功能减弱,均可通过对细胞周期的调控作用使细胞 Thyroid tumor is a more common endocrine neoplasm, the incidence in the general population of 4% to 7%, most of them are benign, but about 5% of malignant, that is, a variety of thyroid cancer. The formation of tumors in a variety of reasons caused by increased cell proliferation and transformation of protein expression, increased function. Or inhibit the proliferation and transformation of cells decreased protein expression, decreased function, both through the regulation of the cell cycle so that cells
