Up to 90% of cancers are caused by modern lifestyle choices such as smoking, drinking and spending too much time in the sun, according to a new study.
The findings contradict research published earlier in the year which claimed that two-thirds of cancers were caused simply by "bad luck".
The paper came to the following conclusions about the split between environmental and natural causes for certain types of cancer:
:: Colorectal cancer: 25% naturally - 75% poor diet
:: Skin cancer: 14% naturally - 86% ultraviolet radiation from the sun
:: Cervical cancer: 10% naturally - 90% human papilloma virus
:: Oesophageal cancer: 25% naturally - 75% tobacco and alcohol
:: Liver cancer: 20% naturally - 80% Hepatitis B and C, alcohol
:: Anal cancer: 10% naturally - 90% human papilloma virus
:: Lung cancer: 14% naturally - 86% smoking
In an earlier study from January, researchers at the Johns Hopkins University School of Medicine in Baltimore looked at 31 cancer types and found that 22 were generally "bad luck".
