Mutational signatures can shed light onto mechanisms of carcinogenesis and reveal the mutagenic impact of novel and established environmental risk factors. A new study examines the mutational spectra of esophageal squamous cell cancer together with exposure information in regions of high and low incidence of the disease, and demonstrates both the limitations and potential of mutational signature analyses.
