I think it is true that the waves to which we are exposed due to cell phones and other stuff like microwaves for example may raise the possibility of getting cancer. Yet I think that some people are more inclined to get it than others. Depending on your genetic disposition, it might be that people who reason their illness with the waves from cell phones might have got ill without them too. I think the industrial environment offers so many different factors for getting cancer. Mostly it is probably a mixture of environmental factors and genetics.
