One private practice ENT is hardly a credible source of information on the effects of cell phone radiation. Remember that many ENT's who think that UPPP is a good idea, and often don't see any need for CPAP'ers to have fully data capable machines.
Practicing physicians in general have a really bad grasp of science, especially mathematics and probability. They are fairly good at assembly line medicine. Luckily, most of us only need assembly line medicine most of the time.
The true experts who do actual research almost never find a link with health problems from cell phone exposure. Even when they do find some a difference in cancer rates, the difference is small, and usually of questionable statistical significance, especially when you ignore the 100 studies that show no effect and cherry pick the one study in 100 that shows some very minor effect.
Yes, you can worry about some highly improbable risk of cell phone cancer, or plastic fumes. You can worry about lots of things.
There are lots of car accidents, you should stop driving, or at least not use the car unless absolutely necessary.
Flu kills 20,000 people a year in the US, better get vaccinated. No wait, there are a few people who react to vaccines, better not.
Mosquitoes kill 1 million people a year worldwide. Better put on the insect repellant. No wait, there's this article saying there might be some risk.
Shaking hands can spread deadly germs. I'd better not shake hands any more.
Electricity causes a lot of fires, better not use it.
Lots of people fall in the shower. Better shower only when absolutely necessary.
Germs get spread by people in restaurants. Better not eat out.
A few people have severe reactions to peanuts, shellfish, and tree nuts. Better not eat them.
Sunlight causes cancer. Better use sunscreen. No wait, there's a study that questions the safety of sunscreens.
There may be radon in my house, better open the windows and turn on a fan. No wait, there are allergens and germs out there.
Gas furnaces can create CO, better not use that.
People die from paper cuts. Better quit reading.
Your air conditioner can grow deadly germs and molds in the ducting, better stop using that.
Cooking food creates carcinogens, stop cooking food.
Raw vegetables can contain salmonella and other germs, stop eating them.
Mad cow disease, no beef or lamb.

Kissing can spread germs. Better not kiss anymore. No sex, either.
Pregnancy can be dangerous. Better not have kids.
Kids (and other family members) can bring home germs. Better live alone.
Spend that effort you're using to worry about improbable threats like cellphones and plastic fumes and work on real things you can change like maintaining a healthy weight, eating right, driving carefully, exercising, home safety, proper healthcare, CPAP usage, etc.
