Background In order to review the epidemiologic evidence concerning previous lung
diseases as risk factors for lung cancer, a meta-analysis and systematic review was …

Research has found that certain bacteria are associated with human cancers. Their role,
however, is still unclear. Convincing evidence links some species to carcinogenesis while …

Microbes are residents in a number of body sites, including the oral and nasal cavities,
