Christine Posted November 5, 2007 Share Posted November 5, 2007 http://www.thisisexeter.co.uk/displayNo ... eId=142333 Smoking has been found to account for 90 per cent of lung cancers.The rate of lung cancer in non-smokers rises significantly with frequent exposure to secondhand smoke, such as living with a smoker. 10 separate studies have shown an increase of up to 30 per cent in the risk of lung cancer among non-smokers living with smokers, compared with non-smokers living with non-smokers. Once someone has smoked the equivalent of 20 cigarettes a day for 20 years, their chances of getting lung cancer rises with the number of cigarettes smoked per day and the number of years smoking. Smoking 20 cigarettes a day for 40 years increases your risk of getting lung cancer 55-fold. The risk of getting lung cancer does not lower substantially until a smoker has quit for 12 years. Female smokers are twice as likely to develop lung cancer than male smokers. Smoking has been identified as the most significant cause of preventable disease and premature death in the UK. One third of cancer deaths are linked to tobacco smoking. Quote Link to comment Share on other sites More sharing options...
