Smoking is the single biggest avoidable cause of cancer.
In the UK more than a quarter of cancer deaths (about 29%) are caused by smoking. It is responsible for about 9 out of 10 cases of lung cancer (90%) and also plays a role in many other cancers, such as cancer of the mouth, throat, bladder, kidney, pancreas, bowel, stomach and cervix.
Breathing other people’s smoke (passive smoking) also increases your risk of developing cancer. If you smoke, giving up is the healthiest decision you can make.
Help is available if you want to give up smoking. Ask your GP for advice, or call the NHS smoking helpline.
