甲状腺瘤疾病的诱发因素很多，到底怎么诱发的呢

    
    From a medical perspective: one or more carcinogenic factor, such as radiation damage, such as iodine or a genetic role in thyroid cells, causing intracellular杭州哪里可以挂甲状腺疾病专科 DNA permanent changes, then with growth stimulating effect of thyrotropin ( normal or excessive ) long-term stimulation, lesion development, disease eventually develop into malignant tumors.

    Then the specific causes which aspects:

    Radioactive material:

    A large number of facts prove, X ray irradiation and future occurrence of thyroid tumors of the relationship is very close, especially for children affected significantly more than adults. According to the report of 70%~80% in thyroid cancer in children, have early due to cervical lymphadenitis, tonsillitis or thymic disease underwent radiation treatment history. To diagnose cancer radiation therapy for a mean time of 8.5 years. Older patients for treatment of acne or cervical arthritis disease received radiotherapy, is also associated with thyroid cancer, radiation injury and incidence of cancer among the average time for 12.3 years. To Hiroshima from Japan, Nagasaki survivor studies suggest, because suffer to the atomic bomb explosion after ionizing radiation, thyroid cancer incidence greatly increased.

    ( 2) iodine deficiency:

    Iodine induced thyroid cancer has been recognized, such as Swiss goiter endemic areas, the incidence of thyroid cancer was 2%, compared with Berlin in non-endemic areas up to 20 times, due to iodine deficiency, the pituitary secretion of excess TSH, long-term stimulation of thyroid cell, fully by students and some variation in cancer cells proliferation.

    ( 3) induced goiter in stimulus:

    Long term application of induced goiter ( class of drug propylthiouracil ) can lead to the occurrence of thyroid cancer in experimental animal, the carcinogenic mechanism and roughly similar due to iodine deficiency, thyroid cancer, the mechanisms of carcinogenesis and roughly similar due to iodine deficiency, thyroid hormone is reduced, the increase of TSH, causing thyroid hyperplasia, part hyperplasia cells mutate, then the occurrence of杭州哪里可以看甲亢 thyroid cancer. Clinically it with goitre caused by drugs, there is no carcinogenic reported, in inborn errors of thyroid hormone biosynthesis metabolic disorder caused by a congenital cretinism or hypothyroidism in tissue sections, can also be seen in extreme hyperplasia nodules, some patients may still be seen good differentiation of follicular carcinoma and papillary adenocarcinoma change.
