Modern life causes 90 per cent of common cancers, not faulty genes

The paper, published in the journal Nature, challenges the controversial theory that a large proportion of cancers are the inevitable result of cellular mistakes in the human body. Researchers at Stony Brook University in New York examined the genetic “fingerprints” of several cancers to calculate how much of the risk was down to environmental factors.
They estimated that between 70 and 90 per cent of the most widespread cancers had extrinsic causes, which include ultraviolet radiation, pollution, stress and other factors that are within people’s control. However, other kinds such as brain cancers are much more likely to be the result of the body’s natural repair mechanisms going haywire.
