The risk is MUCH greater than you indicate. The data I've seen indicates that the risk is about 10 times greater for smokers (not 50%). This assumes a typical pack a day smoker. This risk goes up or down depending on the quantity smoked. Also, I don't believe that the non-smoking population has anywhere near a 5% chance of getting lunch cancer. For a non-smoker the rate is around 1 per 10,000 per year. I believe this factors to something less than 1%. Now, for a smoker (1 per 1000 per year), you're probably looking at something in the 5-10% range over a lifetime.
