Lung cancer is the most common form of cancer caused by smoking – more than 80% of lung cancer cases are caused by it.
Smoke contains over 60 chemicals known to cause cancer. Certain chemicals in tobacco smoke damage an important gene called p53. The p53 gene is found in the nucleus of every cell in the human body, and its main role is to prevent cancer cells evolving. Cigarette smoke is the main cause of p53 mutations in lung cancer.
The good news is that it's never too late to stop smoking. The younger you are, and the sooner you stop, the better. Even smokers who quit at the age of 60 can reduce their chance of getting cancer and other diseases.
