The 16 cancers caused by smoking:

Here’s a list of the 16 cancers you’re at risk of getting if you smoke, and the proportion of cases caused by smoking:

• Lung: 4 in 5 lung cancers are due to smoking

• Mouth, throat, nose and sinuses: 65% in men and 45% in women, and voice box: 77% of cancers of the voice box

• Oesophagus (food pipe): 60% of all cancers of the oesophagus

• Stomach: 23% in men and 11% in women

• Bowel (colorectal): Around 6% in men and 7% in women

• Liver: 24% in men and 11% in women

• Pancreas: 23% of cancers of the pancreas

• Cervix and ovary: 17% of mucinous ovarian cancers, a common subtype of ovarian cancer among young women. Smoking causes 7% of cancers of the cervix

• Bladder, kidney, and ureter: 34% in men and 26% in women

• Bone marrow (acute myeloid leukaemia): 16% in men and 4% in women.

By the age of 80 years, it’s estimated that 1 in 2 people who smoke will have been diagnosed with cancer. For more information on the 16 cancers caused by smoking, read our 'Smoking causes 16 cancers' fact sheet.

The good news is, stopping smoking reduces your risk of cancer over time. The earlier you stop smoking, the lower your risk.

"After many attempts, I finally managed to stop in 2012. I’m so very glad that I did, because there’s a good chance I may not be here to tell my story if I hadn’t."
