It is never too late to quit smoking, and the sooner you quit, the more you cut your risk of cancer.
It is also important to avoid second-hand tobacco smoke. Even if you don't smoke, breathing in other people's cigarette smoke can increase your risk of cancer.
About one in eight deaths from cancer are due to smoking. Smoking causes cancer of the lung, larynx, throat, mouth, nose, ovary, bowel, ureter, bladder, liver, kidney, oesophagus, pancreas, tongue, cervix, bone marrow (myeloid leukaemia) and stomach. More than 15,000 Australians are diagnosed with a smoking-related cancer every year.
