16 cancers

Smoking causes 16 types of cancer

Tobacco smoke contains more than 7000 chemicals, including over 70 carcinogens or chemicals known to cause cancer. When you inhale cigarette smoke, these chemicals enter your lungs and spread through your body. Many of the chemicals in tobacco smoke are toxic and can cause damage to your cells leading to the development of diseases like cancer.

There is no safe level of smoking. Click on the highlighted areas below to learn more about the 16 cancers which can be caused by smoking.

Lung

Lung cancer is the leading cause of cancer death in Australia and one of the most common cancers in men and women. Four in five lung cancers are caused by smoking.

Mouth

Cancers of the mouth include tumours of the cheek, gum, tongue, lip, and the floor and lining of the mouth.

Throat (Pharynx)

Cancers of the throat include tumours in the area behind the nose and mouth that connects to the oesophagus. Your risk of throat cancer greatly decreases over the first 10 years after stopping smoking.

Voice box (Larynx)

Around three-quarters of cancers of the larynx are due to smoking.

Nose

Smoking causes sinus cancer and cancer of the nose.
