Abscopal effect
The abscopal effect is a hypothesis in the treatment of metastatic cancer whereby shrinkage of untreated tumors occurs concurrently with shrinkage of tumors within the scope of the localized treatment. Robin H. Mole (1914–1992) proposed the term abscopal ('ab' - away from, 'scopus' - target) in 1953 to refer to effects of ionizing radiation "at a distance from the irradiated volume but within the same organism".
