||Abstract: "[Investigators] studied the relationship between the number of normal stem cell divisions and the risk of 17 cancer types in 69 countries throughout the world."
||Abstract: "The major role of R [DNA replication errors] mutations in cancer etiology was supported by an independent approach, based solely on cancer genome sequencing and epidemiological data, which suggested that R mutations are responsible for two-thirds of the mutations in human cancers."
