What do you think about the relationship between cell phone utilization and the possibility to develop cancer (particularly in brain...)?

I have heard many different opinions, ones claiming that there is indeed a higher risk, while others stated that the radiation levels are insignificant.

The current status by WHO is "potentially carcinogenic". This means that the studies are inconclusive (i.e. they cannot state whether it is safe beyond any reasonable doubt) and requires more looking into. However, there is also not enough evidence to issue any warning.

To my knowledge there is only one single study which studied long-term effects (10 years). There no link was found, but it was hypothesized that theoretically for heavy users there may be a slightly increased risk (which was likely the reason for the stance of the WHO).

One limiting factor is that cell phones are not that long in massive use yet and that the effects are likely not acute and may have long time delay before manifestation.

There is no easy answer, but chances are that the risks are relatively mild relative to other common potential health risks.

I totaly agree with CharonY. More studies are requires, in order to have a scientific suppor of this hypothetical relationship.

In a way, there is already enough data to form an opinion.
