Isotope therapy, also known as radioisotope therapy or molecular radiotherapy, involves using radioactive isotopes to target and kill cancer cells or abnormal cells in the body. This advanced form of treatment is used to treat various forms of cancer, including thyroid, prostate, and bone cancer. Other synonyms for isotope therapy include targeted radionuclide therapy, radioisotope ablation therapy, and systemic radiotherapy. Isotope therapy is a highly specialized and effective treatment option, which works by targeting cancer cells without harming the healthy cells surrounding them. This precise targeting makes it a safer alternative to conventional cancer treatments such as chemotherapy and radiation therapy.
