Cell phones emit radiation constantly, even when you are not talking or using the phone.
A powered-on cell phone is always “checking in” and maintaining a connection to the nearest cell tower by sending intense bursts of radiation several times per second. Updates for apps happen regularly without us even knowing. Likewise, a wireless-enabled laptop, tablet or other device is always “checking in” with the nearby router or a network access base. These “check ins” are RFR emissions — happening several times per second and whether or not a connection is successfully established.

Published case reports detail how young women with no family history getting a diagnosis of breast cancer are developing unusual breast cancers directly on their chest, underneath the skin area where they placed their cell phones in their bra.
