People who smoke are particularly at risk of lung cancer, throat cancer and oral cancer, which hardly ever affect non-smokers.
90% of lung cancer cases are due to smoking. Only 0.5% of non-smokers can develop lung cancer.
The risk of oral cancer is four times higher in a smoker than for a non-smoker. Cancer can start in any area of the mouth, with the most common being on or below the tongue, or on the lips.
