In theory no. Since the radiation from cell phones is non-ionizing it isn't energetic enough to rearrange molecules. In general non-radiation that isn't powerful enough to heat tissue isn't thought to be dangerous. The radiation in your microwave oven is non-ionizing as well, you wouldn't want to put your hand in a oven when it is on because the frequency is such that it is easily absorbed by tissue and it is powerful enough to excite molecules enough to heat tissue. It is the heat not the radiation that is considered dangerous. Cell phones use frequencies that are not as efficiently absorbed by tissue and to maximize battery life modern cell phones only transmit with enough power to reach the nearest tower.
There is a positive correlation between between heavy cell phone use and increased rates of brain cancer. You should understand that correlation does not prove causation. The reason heavy cell phone users get more brain cancer could be because of other factors. People who use cell phones a lot may have other lifestyle differences that account for the increased cancer rates. For example, people on the cell phone a lot might often be workaholics who do not get enough rest or eat too much fast food.
People are still studying this issue but based on everything we know about cell phones, radiation, and physiology it is very unlikely that using cell phones cause health problems.
Well I don't believe they do cause any health issues.
But the low power electromagnetic waves (typically less than a couple of watts) are radiated from a point that is very close to the brain when the cellphone is held to the ear. A small proportion of that low power signal induces small electrical currents into the brain tissues, and some scare-mongers claim that this is dangerous and can cause tumours.
Of course in the event that someone gets a brain tumour, (whatever the cause), .....
.....with the modern "where there is blame there is a claim" culture there are all sorts of people who will want to sue the ruthlessly reckless (& rich) manufacturers for compensation because everyone "knows how dangerous their cellphones are" and that must be what cause it.
