I very rarely use my cell phone as a phone.

Except for during the planning of our wedding I never had a need for one until my husband got an iPhone. Once a cell phone could do more and be more than be a phone that's the only time I wanted one. I'm writing this on my phone, as a matter of fact.
So the fact that they are saying, again, that cell.phones give you cancer doesn't concern me. Not only because I really don't use one as a phone but because I learned a long time ago that these studies are rarely just what the headlines say. I always remember an article I read when I first started reading the newspaper that had the headline that bacon causes cancer. I really love bacon so this concerned me, even when I was ~10 or so. So I read the whole article and found that they had force fed the mice or rats over twice their body weight in bacon fat daily until something happened and that something was cancer. Even that young it was pretty obvious to me that if you an average adult ate 200+ pounds of bacon a day something bad is going to happen.
They have been saying that cell phones cause cancer for about 10 years. It hasn't stuck yet.
