Cancer kills more than half a million men, women, and children each year in the U.S, and chemotherapy is only slightly more discriminating than the disease it treats. As a result, many cancer treatments kill cells throughout the body and cause severe side effects. New IRP research could solve this problem by creating a way to release those toxic compounds only when and where doctors desire.
