Radioactive Iodine Therapy is a medical treatment primarily used for conditions related to the thyroid gland, such as hyperthyroidism and certain types of thyroid cancer. The therapy involves administering a small dose of radioactive iodine, which is absorbed by the thyroid cells. This helps to destroy overactive or cancerous cells while sparing surrounding tissues. The treatment is usually given in a single dose, either in liquid form or as a capsule. Patients may need to follow specific safety guidelines after treatment to minimize radiation exposure to others. Overall, Radioactive Iodine Therapy is considered a safe and effective option for managing thyroid-related disorders.
