Cancer

This ecological study investigated trends in brain cancer incidence to evaluate the potential impact of increased mobile phone use in Spain since the early 2000s. It analysed brain cancer incidence data from 12 Spanish cancer registries, covering the period from 1985 to 2015. The analysis was stratified by age group, with separate evaluations for adults (aged 15 years and older) and children (aged 0 to 14 years). The dataset included 20,325 adult and 2,372 childhood brain cancer cases.

This computational modelling study evaluated the relationship between current computed tomography (CT) scanning practices and future incidence of cancer in the USA. Data on CT use was extracted from a market outlook survey of hospitals and imaging facilities in the USA. CT scans were subdivided into categories and an average dose per category was determined using data from a US CT dose registry.

This cohort study examined rates of cancers among people who lived in apartments and were exposed to extremely low frequency electromagnetic fields (ELF EMFs) from electricity transformers. The exposed population was categorized into three groups: most exposed (individuals living in ground and first-floor apartments adjacent to the transformer room, n = 8,840), unexposed (individuals living on higher floors, n = 179,285), and partially exposed (individuals living on the ground and first floors but not adjacent to the transformer room, n = 52,599 Cancer diagnosis was based on entry in the Finnish Cancer Registry. The study compared the number of cancers that occurred in the apartment buildings to the average numbers that occur based on the Finish Cancer Registry. The study found no association between ELF EMF exposure and cancer incidence when all cancers were examined together (all site cancers standardized incidence ratio (SIR) 1.01, 95% confidence interval (CI) 0.93-1.09). However, when cancers were examined individually, a statistically significant association was observed for the exposed group with digestive organs cancers (SIR 1.23 95% CI 1.03-1.46) [overall], and more specifically with gallbladder cancer (SIR 3.92, 95% CI 1.44-8.69), and small intestine cancer (SIR 2.67, 95% CI 1.08-5.56). Overall, the study reported no elevated risk of cancers associated with the ELF EMF exposure due to living near an electrical transformer; however, it showed an elevated risk of digestive organ cancers due to the ELF EMF exposure.
