Breast Cancer: Studies have proven a linkage between breast cancer in women and prolonged contact between their breasts and their cell phones. One study investigated multiple cases where women who regularly carried their smartphones directly against their breasts for up to 10 hours a day, for several years, had developed almost identical tumors in areas of their breasts underlying the phones.

Childhood Brain Tumors and Leukemia: It is a fact that children absorb more MWR than adults because their brain tissues are more absorbent, their skulls are thinner and their relative size is smaller. In pregnant women, the fetus is particularly vulnerable to radiation.  Microwave radiation exposure can result in degeneration of the protective myelin sheath that surrounds brain neurons. (Source)

Studies looking at the effects of EMF on children, have found a notable connection between EMF exposure due to cell towers (Source) and childhood leukemia. This has been a controversial topic since the 1980s.

Coincidentally, in a smaller study, researchers found that people exposed to high levels of EMF for years at a time (mostly career related) showed an increased risk of a certain type of leukemia in adults. (Source)

Due to the convincing evidence of linkage between EMF exposure and brain tumors, the WHO has launched a study that focuses on brain tumors specifically in children at today’s typical level of RF exposure, called Mobi Kids. This study is currently active.
