When i'm on the cellular level, how does radiation and chemo work in fighting cancer?

When i'm on the cellular level, how does radiation and chemo work in fighting cancer?

Chemotherapy agents: Work by several different mechanisms. Some block cell cycle progression, for example by inhibiting dna synthesis or mitotic spindle function. Others damage dna (eg., by covalent modification or strand breaks) and activate checkpoint controls to prevent those errors from being propagated and instead causing apoptosis. Radiation works similarly. Some, but not all agents work best on dividing cells. ...Read more
