When mobile technology first became popular, there were many studies that claimed that increased cellular use could lead to cancer. This was a highly controversial statement – with many individuals cancelling their mobile subscriptions until empirical data suggested otherwise.
Several more studies were undertaken. Most of these concluded that the amount of cellular exposure to develop cancer was almost impossible to attain; that is, the individual should be constantly and continually be on the phone for almost the entire day for several months. As far as mobile companies were concerned, the issue was over.
Recently, however, a major US government study reopened the topic, claiming the excessive cellphone exposure does indeed lead to cancer, at least among rats. Researchers of the study concluded that continuous exposure to radiofrequency radiation increases the potential of developing certain forms of cancer, particularly in the brain.
The upside is that the risk is relatively small, and the exact translation of the phenomenon to humans is still undetermined. Still, medical researchers are cautioning the public to be more vigilant with their cellphone usage. They argue that their findings do suggest that there is a correlation (and perhaps an undetermined causation) between mobile use and developing cancer.
Further research still needs to be made, but this recent finding has caused a major ripple among cellular companies. People are once again questioning the health and safety hazards of using their cellphones.
