Since radioactivity was discovered, the field of nuclear medicine has contributed for the diagnosis and treatment of an array of diseases and disorders. In terms of diagnosis, certain isotopes are chosen because they have an affinity for a specific organ or tissue as a target. In terms of treatment, cancerous tumors are exposed to radiation to control and/or kill the malign tissue. For this discussion, explain which specific isotopes are used to diagnose and treat a specific illness of your choosing. Also, discuss the properties of the specific isotope, which makes the treatment and/or diagnosis possible
