Yes.
The risk is DIRECTLY proportional to the number of cigarettes. and because the breakdown of nicotine (cotinin) is not naturally present in the body, stays around for hours after smoking and can be easily and precisely measured, we can get a measure of how much one is exposed to smoke and directly relate that to the rate of cancer. It is there, but the risk is quite small (maybe 1% lifetime), it is just very precisely calculable.
