Cellular Devices: Cancer Causers?

In recent studies esteemed scientist Laura Marshall tells us that the usage of cellular devices may in fact cause brain cancer. She strongly advises that no adults, and especially no children use mobile devices. She clearly states that she does not allow her children to ever use mobiles because she knows that they cause cancer.
Her research is little, but she seems to be fully affirmed in the fact that this is right? How does she know? Because it makes sense! The microwave rays from the cellular devices obviously are emitted whenever they are used, and get inside your brain, creating tumors the size of Mongolia, that will end up ruining your life forever! It's super tough to remove brain tumors, she says, why take the risk? Why must you be able to contact people twenty four seven? Do you really rely on people that much? Mrs. Marshall is a very religious woman, and believes that you always have a cellular device with God, because you can talk to Him whenever need be!
She also warns people that microwaves may not be as safe as we think they are, and an oven is a safer device to use than that of a microwave, for the same rays from the cellular device may affect your brain when they emit from the microwave, or may get in your food!
These rays emitted from cellphones seem highly dangerous! For all we know, the millions of people who use cellphones a day could have tumors growing in their heads as we speak, amassing to great sizes, eventually ending up ruining there lives! Should we ban cellphones completely? It's a topic of major speculation! It is very much possible that these devices we use may be the end of our population, if too many of us use them! Mrs. Marshall firmly stands against cellphones, and urges all other caring parents, and people in general, to stay as far away from them as possible, and keep loved ones from using those “death devices”!
