Radioactive iodine can be helpful and harmful to thyroids

Radioactive iodine, which is also known as I-131, is used in the treatment of thyroid cancer, reports EmpowHer. However, the compound is also a cause of the condition, as it was found in survivors of nuclear bombing, such as the events that occurred at Hiroshima and Nagasaki.

Yet researchers agree that high doses of I-131 can be useful in eliminating malignant tissue after thyroid-removal surgery. In order to determine the correct dosage, doctors can utilize bone marrow or lesion-based methods.

In the treatment of thyroid cancer, radiation therapy is usually performed through the use of an external beam, according to the news source. The tissue then absorbs the iodine, which brings radioactive energy to the tumor cells. The process is painless, as it involves the patient swallowing a prepared dose.
Radioactivity can last up to several months, the media outlet reports. This can result in setting off security detectors at airports or federal buildings.
Thyroid cancer is the fastest-growing cancer in the U.S., according to the American Cancer Society, which estimates that 44,670 new cases will be diagnosed nationwide this year.
