Background: Air pollution, including particulates and gazes such as ozone (O), is detrimental for patient's health and has repeatedly been correlated to increased morbidity and mortality in industrialised countries. Although studies have described a link between ambient particulate matter and increased lung cancer morbidity, no direct relation has yet been established between O exposure and metastatic dissemination to lungs.
Objectives: To outline the mechanisms through which pulmonary O exposure modulates metastasis kinetics in an experimental mouse model of O exposure.
