Could height be a cancer risk?

According to Ian Westbrook a health reporter for BBC, taller people are at more risk of getting cancer, a new study looking at over a million people claims. Past reports have reached the same conclusion, but should lofty people be alarmed, or is this just a tall story? Experts stress the results only point to a very small increase in risk compared with factors like smoking. Plus it is unclear what might be the driver behind the link. The leading theory is tall people have more cells that can turn cancerous. But hormone levels, other illnesses and how affluent or deprived people are when young, might have an impact on height and cancer risk too. Report author Dr Leonard Nunney told the BBC a person's risk factor depended on their exact height.
