Is iodine 131 radiation or chemotherapy?

Iodine 131 is radiation therapy.

Iodine 131 is highly selectively absorbed by thyroid tissue. Using this property, after iodine 131 enters the thyroid, its beta rays can destroy part of thyroid tissue, thus achieving therapeutic purposes. Mainly used for hyperthyroidism, especially for patients who are ineffective or relapsed with drug treatment, unsuitable for surgery or contraindications for surgery;

Compared with traditional radiotherapy, it has the advantages of strong pertinence and relatively small damage to surrounding tissues. It can accurately act on thyroid lesions. Patients need to undergo corresponding examination and evaluation, and then give appropriate doses of iodine 131 according to specific conditions. Following treatment, isolation and precautions should be observed.

Iodine-131 treatment may cause hypothyroidism, which usually requires long-term thyroid replacement therapy; in rare cases, radiation thyroiditis may occur. Iodine-131,

as a special radiotherapy method, plays an important role in the treatment of thyroid diseases, but the indications and possible side effects should be strictly controlled to ensure the safety and effectiveness of treatment.
