Does the use of mobile phones cause cancer? A large number of studies so far found evidence both for and against. Now a neurosurgeon based in Australia, Vini G. Khurana, has linked their continuous use with considerably higher chances of certain types of cancer on the basis of his review of 100-plus such studies. His yet-to-be published paper can be read on the website, www.brain-surgery.us. Industry bodies may reject it outright, but Khurana raises pertinent issues—especially of rationalizing the use and of more research on cellphone safety. The Independent, UK, which reported his work on Sunday, had covered a study by two Swedish scientists in October, who said the global norms to protect users from radiation need to be much tighter.
On Friday, several Indian doctors urged health minister A. Ramadoss to ban promotions and ads that encourage use of cellphones by children—they are more vulnerable. Caution does make sense here, till there’s more conclusive evidence on the safety of use.
