Analyses have found a direct link between the number of cigarettes smoked during one's lifetime and the number of mutations in tumour DNA. Commenting on these findings, Prof. Sir Mike Stratton from the Wellcome Trust Sanger Institute notes that: "The more mutations there are, the higher the chance that these will occur in the key genes that we call cancer genes, which convert a normal cell into a cancer cell."
