Method For Treating and/or Imaging Breast Cancer Using Radioactive Iodine

This invention involves treating a breast cancer patient by the administration of a radioisotope of iodine in a dosage of between 5 and 50 milliCuries over the course of a day.  The therapeutic composition is designed for mammary tissue uptake and includes an inorganic radioactive iodide salt (e.g., alkali metal, alkali earth or transition metal iodides) and a parenterally injectible carrier therefor.  Adjuvants are optionally added to increase uptake by mammary tissue or inhibit uptake by the thyroid gland.  The composition may also have utility as a radioimaging dye. A U.S. patent application has been filed.
