Radioisotopes

Rachelk17 May, 2022Health

Therapy using radioactive isotopes to treat certain cancers is called systemic radiation therapy. The radioactive isotopes may be swallowed, given intravenously or injected into the body. For example, radioactive iodine (I-131) capsules are given to patients to treat some types of thyroid cancer. Another example is the use of intravenous radioactive samarium or strontium to treat pain due to cancer that has spread to the bone.
