A few weeks ago, the WHO says the phone is likely to cause cancer. The decision by the WHO put the phone in the same section as coffee, where the effect can not be ruled out, but can not be proven as well.
According to the Institute of Cancer Research, a WHO statement has not been proven because although the use of cellular phone rise very sharply but there is no spike in the number of tumors.
Of the largest is the interphone study, a comparison of 2708 patients with
brain tumors with the same number of people without brain tumors. The study concluded that mobile phone radiation on a regular mobile phone users are less likely to get brain tumors, but the risk is increased in heavy users.
Further research is necessary, but so far is lovely. Quoted from the BBC news, UK's cancer researcher Dr Joanna Owens said: "Although the researchers acknowledge that they can not rule out the idea of the relationship between cell rings and brain cancer". They remind us that in most studies, including in their large international studies, mobile phone users do not appear to increase the risk .
They do not yet have information that is very long-term use of cell rings, or for effects on cancer risk in kids, so it may be wise to encourage kids to limit their mobile phone call time. The phone does not appear to cause brain cancer in the first 10-15 years after people began using them.
