One way it can happen is in response to some outside force, like radiation. If gamma radiation is traveling through living tissue, it's like you're hurling a cue ball (radiation) into a set of pool balls (DNA). The radiation can damage the DNA in such a way that it's not totally "broken", but is different than it was before and yet still functional. This means it could transform the cell's normal operations into overdrive resulting in a cancerous tumor, or it could just subtly change how the cell reproduces so that a new characteristic is created and propagated to daughters of that cell, which might be beneficial or harmfull to the host organism.
