"Medical authorities in the Shiraz area estimate that local satellite jamming activity is likely to result in at least 24,000 cancer cases in the coming years, and a senior Iranian health official has stated publicly that, “recent studies show that jamming signals and waves have side effects and can increase the risk of cancer.”

What I'm interested in is what's referred to here as the 'recent studies'. Medical research is important here because there have long been concerns around electromagnetic waves causing cancer, but none to my knowledge have held up. Such as living under power lines or near radio stations, cellphones. That's not to say the radio jamming in this case is not using a dramatically more dangerous method.
