Not smoking is the most effective way to avoid getting lung cancer.
If you are a smoker, the best way to prevent lung cancer and other serious conditions is to stop smoking as soon as possible.
However long you have been smoking, it is always worth quitting. Every year that you do not smoke, your risk of getting serious illnesses, such as lung cancer, will decrease. After 10 years of not smoking, your chances of developing lung cancer falls to half that of a smoker.
A great place to start is to check out the Quit Now website and its variety of information and tools to support you in quitting smoking.
Your doctor or pharmacist can also give you help and advice about giving up smoking.
Research suggests that eating a low-fat, high-fibre diet, including at least five portions a day of fresh fruit and vegetables and plenty of wholegrains, can help reduce your risk of lung cancer, as well as other types of cancer and heart disease.
There is strong evidence to suggest that regular exercise can lower the risk of developing lung cancer and other types of cancer.
Adults are recommended do at least 150 minutes (2 hours and 30 minutes) of moderate-intensity aerobic activity each week.
