Put simply, yes, but it's difficult, if at all possible, to ascribe any cause-effect relationship there. In the time between the introduction of cigarettes and the present day has seen the functional elimination of most of the major killers of humans(most major diseases, small pox etc. Also war is at a virtual 0 today relative to the past, and nutrition is at its best in history even in "third world nations") certainly in the western world. This is a bit more of a medical question than a historical one, but the fact is that pretty much everything that exists causes cancer eventually, and smoking leads the pack in terms of modern cancer causes. The spike in cancer deaths/occurrences is mostly due to increasing lifespan allowing for more time to GET cancer. If we were to cure every disease that exists, then everyone would die of either cancer or accidents.

So yes, cancer rates are MUCH higher than in the past but this is more due to people not dying of other things than it is because of cigarettes(which isn't to say that it isn't a factor, simply that it's tough to draw a causal relationship).
