Radiation is a potential cause of cancer, and secondary malignancies are seen in some patients. ... Isotopes commonly used in the treatment of bone metastasis are ...
Radiation hormesis is the conjecture that a low level of ionizing radiation (i.e., near the level of Earth's natural background radiation) helps "immunize" cells against DNA damage from other causes (such as free radicals or larger doses of ionizing radiation), and decreases the risk of cancer. The theory proposes that such low levels activate ...
A radioligand is a microscopic particle which consists of a therapeutic radioactive isotope and the cell-targeting compound - the ligand. The ligand is the target binding site, it may be on the surface of the targeted cancer cell for therapeutic purposes. Radioisotopes can occur naturally or be synthesized and produced in a cyclotron/nuclear ...
It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems. [1] Another well-known radioactive isotope used in medicine is Iodine-131, which is used as a radioactive label for some radiopharmaceutical therapies or the treatment of some types of thyroid cancer.

Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer.Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.
Some α emitting isotopes such as 225 Ac and 213 Bi are only available in limited quantities from 229 Th decay, although cyclotron production is feasible. [9] [10] [11] Among alpha-emitting radiometals according to availability, chelation chemistry, and half-life, 212 Pb is also a promising candidate for targeted alpha-therapy.
Germanium-68 is commonly used to calibrate medical imaging scanners and to create other isotopes used in nuclear medicine studies. The item in question – described as a "pin source" – measures ...
Iodine-125 is also commonly used by radiation oncologists in low dose rate brachytherapy in the treatment of cancer at sites other than the thyroid, especially in prostate cancer. When 125 I is used therapeutically, it is encapsulated in titanium seeds and implanted in the area of the tumor, where it remains. The low energy of the gamma ...
