Cancers caused by smoking
Smoking is a prime cause of lung cancer but it is also a known risk factor in several other cancers. Find out more about the link between smoking and cancer.
Cancer is a major cause of death and illness in Ireland and many other countries. Your chances of getting the cancers listed below are higher (in some cases much higher) if you smoke.
Lung cancer is one of the most common cancers in Ireland. In 2011, 2,175 people developed lung cancer and 90% of these cases are directly caused by smoking.
It is not only smokers who are affected. Non-smokers who breathe in other people’s tobacco smoke, or ‘second-hand’ smoke, have an increased risk of lung cancer. Children and teenagers exposed to second-hand smoke may be particularly at risk of lung cancer later in life as well as have an increased risk of asthma and other respiratory problems.
