Most Cancers Caused by Bad Luck

Researchers at the Johns Hopkins University School of Medicine have found that the majority of cancers occur as the result of plain bad luck, and not because of an unhealthy lifestyle or for genetic reasons. Of 31 cancers studied by the scientists, 22 are caused by random mistakes in cell division beyond human control. The other nine cancers, which include lung and skin, however, are likely caused by either genetics or lifestyle factors, and have a higher risk associated with them.
