It is a word of Latin roots meaning outside of the object or purpose. Off target or target. It is a term used in cancer medicine. It is actually a beneficial effect that occurs in cancer treatments with radiation therapy, in the sense of reducing or erasing tumors that are not within the irradiated area but outside it (tumors from other areas).
From the Latin prefix ab , outside and scopus , white , target , target : which is outside the target . In medicine there is talk of abscopal effect, an expression coined by Robin Mole in 1953, to signal therapeutic effects outside the radiated area in cancer patients, such as shrinking or disappearing tumors when the immune system is effectively activated.
