What different types of medical isotope treatments are there?
Brachytherapy is a form of cancer treatment where tiny “seeds” containing medical isotopes are accurately placed within and near a tumor. Brachytherapy is FDA approved and used for localized prostate cancer, liver cancer, head and neck cancers, gynecological cancers and others. Radioimmunotherapy is a type of treatment where doctors inject antibodies that have isotopes attached like little backpacks. The antibodies (called monoclonal antibodies) then flow through the bloodstream and attach themselves to the cancerous cells. The energy from the medical isotopes is thus targeted straight to the cancer. This type of treatment is showing great promise for blood cancers such as leukemia, lymphoma, and multiple myeloma. Most Radioimmunotherapy treatments are still in clinical trials. Medical isotopes can also be directed to cancerous cells by a carrier that has an attraction to a certain part of the body. Chemical phosphonates can be paired with medical isotopes and sent to the bone, since p
