Wearing earphones is bad for you

Wearing earphones is a habit for many people nowadays, people are enjoying musics, news with it. 

But in the past months, I have received at least three young people who have got thyroid cancer, they have no other bad habits except wearing earphones all day long, I think it is radiation of earphones makes them to get thyroid cancer.

So I advise people use less earphones but use speaker to avoid thyroid cancer happens. One of these three people has used CANTICER(CT) for almost 8 months after thyroid surgery, he does not see any other cancers back.
