Cancer affects organs. If a cancer affects an important organ, let’s say tumours on your liver it can affect its function. Malfunctioning organs will kill you. Radiation breaks down the DNA of cells. If you break down the DNA, the cells have no way of replicating. If the replication is halted, essentially cancer is stopped.

PS: please feel free to correct me if I got anything out of turn.
