Can cell phone use be the cause?
I think tumors occur anywhere
this is the thing with cancer.. a woman gets a lump in her breasts.. is it malignant or not..
I wouldn't use a mobile phone much anyway. And kids certainly shouldn't use them too much - given the unknown. But the fact that most people in the western world are using them, and not suffering terrible brain problems, suggests that any harm it does cause is minimal, or that if they do cause harm, it is over such a long period that we haven't seen the effects yet.
Even microwaved food.. What does it do to the food?
most people are OK with it. But I knew a girl that was -very unhealthy-, that actually got ill eating microwaved food, I don't know if it was the microwave that did it, or the food.
Most important things are diet and exercise, to prevent cancer/ tumors. I think cancer is all about tumors. You can't blame mobiles for it.
