Smoking causes at least 15 different types of cancer: lung, larynx, oesophagus, oral cavity, nasopharynx, pharynx, bladder, pancreas, kidney, liver, stomach, bowel, cervix, leukaemia, and ovarian cancers.
Incidence of some smoking-related cancers is decreasing thanks largely to decreases in smoking prevalence; these include lung cancer (decreasing in males), oesophageal cancer (decreasing in females), and bladder cancer. However, unless there is further progress in reducing smoking prevalence, these decreases are expected to slow and eventually stop.
Tobacco is the largest preventable cause of cancer and death in the UK.[1, 2] and one of the largest preventable causes of illness and death in the world.  Smoking caused an estimated 125,000 deaths in the UK in 2015 - around a fifth (21%) of all deaths from all causes. It caused an estimated 43,000 cancer deaths in the UK in 2015 - more than a quarter (26%) of all cancer deaths. Smoking (both active smoking and environmental tobacco smoke) causes 3 in 20 (15%) cancer cases in the UK.
