I have read that if you smoke one cigar per day or less, your chances of getting various cancers of the throat/tongue etc are elevated, but nearly as high as those who smoke 2-3 sticks per day, and both of those pale in comparison to the chances for various cancers from smoking and inhaling cigarettes.

I'm not saying that smoking cigars is not hazardous, but research I have read shows it to be far less dangerous than smoking and inhaling cigarettes. It may also be due to the fact that cigarette smokers smoke much more frequently than cigar smokers, and inhale to boot.
