LUNG CANCER - CAUSES • Smoking causes almost 90% of lung cancer deaths. • In Britain, 1 in 5 adults smoke cigarettes - 9.5 million people. • Less than 1% of 11 and 12 year olds in England are smokers, • This rises to 15% by age 15 • Stopping smoking before middle age avoids most of the • risk of smoking-related lung cancer. • Living with someone who smokes, increases risk of lung cancer • in non-smokers by about a quarter. • exposure to passive smoke in the home causes around • 11,000 deaths every year in the UK from lung cancer, • stroke and ischaemic heart disease.
