Thyroid cancer scan study probes breast uptake mystery

This study looks at women with thyroid cancer who get a radioactive iodine whole body scan after thyroid removal. Researchers want to see if the way patients are prepared for the scan—either by stopping thyroid hormone or using a special injection—affects how much iodine is taken up by breast tissue and how it relates to prolactin levels. The goal is to better understand these patterns, not to test a new treatment.
