Occasional smokers 'at significantly higher risk' of developing lung cancer

A new report suggests women who smoke between one and four cigarettes a day are five times more likely to develop lung cancer when compared with non-smokers.

The report by the Royal College of Physicians of Ireland (RCPI) Policy Group on Tobacco occasional smokers says they are at "a significantly higher risk" of developing cardiovascular disease, lung cancer, fertility problems and many other health problems.
