A recent U.S government-funded study conducted by the NTP (National Toxicology Programme) a division of the NIEHS (National Institute of Environmental Health Sciences) provides even more ammunition for the case that cell phone EMF (electromagnetic field) radiation is linked to cancer by causing brain tumours. However, contrary to popular belief, the new findings indicated that the harm was not brain cancer, per se, nor was this the primary cause. The study, one of the most extensive yet, found that above all, cell phone EMF radiation was linked to DNA damage and heart tumours.
