Radiation takes advantage of this difference pretty effectively, destroying the cancer cells and temporarily injuring normal cells. How?
Radiation works by passing waves through targeted tissueTISH-YOU — The accumulation of cells that make up parts of the body, like organs to damage the DNADEE-OX-SEE-RYE-BOW-NEW-CLAY-IK AH-SID — The blueprint of a cell that controls the function of all components within the cell of a cellSEL — One of the most basic components of all living things that together form the entire body and contains many smaller parts that guide its function. This stops the cells from working and multiplying.1 Since cancer cells are duplicating more quickly, they’re actively using their DNA, making them more vulnerable and exposed to the effects of the radiation.
So, when the radiation waves hit a replicating cancer cell, it’s injured beyond repair. However, normal cells are only temporarily injured by the radiation and are able to recover after some time.
