worldwide numbers http://www.sciencedaily.com/releases/2009/08/090825151011.htm

US population that uses a tobacco product = about 19.7% of total population (310 million) or about 62 million. Given the timeline bias, you would have to look at that number of people over decades to determine a cancer number.

Remember that many killer diseases trace their route back to tobacco, and it is not just as simple as counting cancers. Heart disease by itself is huge (combination of diet issues and tobacco). Even if you look at SEER numbers for cancers, it isn't just the obvious, lung, oral etc. Tobacco has been linked to cancers in areas remote from areas of obvious contact such as in ovarian and many more.
