In brief: Directly

The contents of cigarette smoke irritates and damages the cells lining the lungs.
When the cells undergo repair, errors in replication can occur, leading to cancer. This does not happen every time, and your body can generally fix the errors, but occasionally something gets through, and cancer starts.
