Not sure where to post this but I feel like this board is the only place I could find people knowledgeable a little on the topic, and its hard to find info on it on the internet. When I was younger I would use my phone for nearly 8 hours a day or more for 5 years, often staying up very late looking at it. I never really used it for calls, though on 2 occasions I slept with it under my pillow, and I would usually wear earbuds. I have a fear the tally his past use puts me at risk for developing tumors or my blood brain barrier breaking down. Is my fear unfounded and I should just stop using it in the future, or should I be concerned?
