Advances in carcinogenesis: A historical perspective from observational studies to tumor genome sequencing and TP53 mutation spectrum analysis

Over the last century, the history of cancer epidemiology evolved in different stages and concepts from occupational observational studies beginning in the 18th century, in vitro and in vivo experimental analyses and cancer gene analyses, such as Ha-ras or TP53. Mutation spectra of passenger mutations from various types of cancers not only confirm the findings of molecular epidemiology analysis, but also reveal novel profiles that will extend this knowledge to single tumors in all types of cancer.
