Cross et al. present interesting evidence of a dose-response relationship between intake of both red meat and processed meat with risk of lung cancer. They estimate that 10% of lung cancer cases might be prevented if all individuals reduced their red meat intake to that of the lowest quartile. Given the extremely large number of lung cancer cases in their study (6,769), it would be of great interest to know whether the association with meat intake differed by histologic type of lung cancer (squamous cell, oat cell, adenocarcinoma, other). Furthermore, although the authors state that there were no differences in their results by sex for sites other than pancreatic cancer, it would informative to look at the sex-specific results by histologic type.
