How can smoking lead to cancer?

With each puff of a cigarette, you suck chemicals that can cause cancer right in to your lungs. Once there, they harm your genes, which control pretty much everything about you. When certain genes are damaged, your cells start to grow and divide out of control. That alone can lead to cancer.
