Cancer caused by environmental factors such as smoking, radiation and toxic chemicals, not 'bad luck', study reveals

Modern lifestyles are causing 90 per cent of cancers, according to new research.
Poor diet, a lack of exercise, stress and pollution are cited as the main contributory factors for the majority of cancers of the lung, breast and prostate.Researchers at Stony Brook University in New York looked at the genetic “fingerprints” of several cancers to try to work out how much of the risk was associated with environmental factors, The Times reported. Among the external factors are pollution, ultraviolet radiation and stress and then factors within people’s own control such as diet and exercise.
Giving up smoking, taking regular exercise and eating well could all be used as preventative measures in the fight against cancer.
