Paper Talk · May 22, 2026 · 22m

This review examines the evolutionary mechanisms of cancer development, focusing on the critical distinction between tumour initiation and tumour promotion. While traditional research emphasizes genetic mutations as the primary cause, the authors highlight that many carcinogens are not actually mutagens but instead act as promoters that encourage pre-existing mutant cells to expand. By integrating Darwinian principles with modern genomics and epidemiology, the source argues that the tissue microenvironment and chronic inflammation are key drivers of clonal selection. Understanding these…
