may cause cancer (癌症). The advice below may help you.

? Try to keep your conversations short. If you need to talk longer, use an phone instead.

? Change ears when you're using your cellphone. Before putting it to your ear, wait until the person you are calling picks up the phone.

? Your phone gives out radiation when you talk or text (发短信)，but not when you're listening or getting messages. Listening more and talking less can lower the risk of cancer.
