Previously, it was believed that the presence of an oncogenic mutation within a cell was sufficient to drive tumour development. However, it is now understood that tissues may contain cells harbouring oncogenic mutations, but that these cells maintain a normal phenotype until an initiating factor promotes oncogenic transformation (Acha-Sagredo et al, 2021). Changes in the cellular milieu and tissue architecture, such as inflammation or parenchymal density, are thought to alter the behaviour of these cells, affecting the likelihood of oncogenic transformation (Ling et al, 2020; Singh et al, 2019). Nonetheless, the precise mechanisms that underlie cancer promotion, and their association with factors such as smoking or obesity, are not fully understood...Read more
