Tobacco smoking is one of the leading causes of preventable early death and disease in Australia. In 2024, Australians lost almost 150,000 years of healthy life from cancers caused by smoking.
Lung cancer is the most common form of cancer caused by smoking – more than 80% of lung cancer deaths are caused by smoking.
Smoking also causes cancer of the voice box, throat, bladder, mouth, tongue, nose, nasal sinus, oesophagus, ovary, cervix, ureter, bone marrow (myeloid leukaemia), pancreas, stomach, liver and bowel.
How does smoking cause cancer?
Smoke contains over 70 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. The number of p53 mutations rise with the number of cigarettes smoked, increasing the likelihood of lung cancer.
Quitting
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 people who quit at the age of 60 can reduce their chance of getting cancer and other diseases.

Tips:
- Tell people if their smoking or vaping bothers you.
