Nearly 50% of all cancer deaths can be prevented. It is reliably estimated that lifestyle and environmental factors are responsible for 42% of the cancers in the United Kingdom. What is true in the UK is likely to be true in much of the industrialized world.
The research looked at the contribution to cancer made by tobacco, unhealthful foods in the diet, obesity, alcohol, lack of exercise, industrial exposures, radiation and several other factors that make a small contribution to cancer.
Of the 314,000 cases of cancer in the UK in 2010, 134,000 were preventable. Tobacco caused 60,000 premature cancer deaths.There were 29,000 cancers caused by eating red meat or a lack of fruits and vegetables in the diet. Obesity was responsible for another 17,000 premature cancer deaths. Alcohol drinking caused 12,000 premature deaths.
