Go ahead and use your cell phone: it won’t cause cancer, says Indian-born American cancer specialist Siddhartha Mukherjee, who received the Pulitzer Prize for his book, The Emperor of All Maladies: A Biography of Cancer in 2010.
He trashed the theory that the electromagnetic field (EMF) produced by mobile phones can cause cancer. He says there is no scientific evidence for this.
This has come almost a year after World Health Organisation panel added cell phones to a list of things that are “possibly carcinogenic.”
"If mobile phones were to cause brain cancer, as has been suggested, the incidence of the disease should have gone up several times with increase in their usage over the past two decades. This has not happened. On the other hand, data shows increased use of tobacco-a scientifically proven carcinogen-has led to a sharp increase in the incidence of cancers of mouth and lung, among others," he said.
Mukherjee said identifying possible carcinogens is like a crime investigation and all evidence has to be pieced together to reach a conclusion. "There is no single clinching evidence in most such cases," he said, and called for further investigations to establish a link between mobile phone radiation and cancer.
In a recent article in the New York Times, Dr Mukherjee said, “The kind of radiation emitted by cellphones-unlike the radiation emitted by X-rays or nuclear bombs-cannot directly damage the DNA. The frequency of cellphone radiation is more than a million-fold lower,” he added.
On tower radiation, he said there is not too much known about it but studies have shown a largely negative relation.
In 2011, WHO had classified radiation from mobile phones as a possible cancer risk, based on the opinion of an expert group from its International Agency for Research on Cancer. After an inter-ministerial committee appointed by the government of India also pointed to possible health risks posed by mobile phones and towers, it was decided to lower the level of radiation emitted by cell phone towers to a tenth of the prevailing standard-from 9.2 to 0.92 watts per square metre. The industry had opposed the idea.
There are three main reasons why people are concerned that cell phones (also known as “wireless” or “mobile” telephones) might have the potential to cause certain types of cancer or other health problems:
