"no clear evidence that cell phone use increases brain tumor risk"
"More research is needed to fully study the possible risks of cell phone exposure for people today."
"The International Agency for Research on Cancer (IARC) classifies RF radiation as "possibly carcinogenic to humans," based on limited evidence of a possible increase in risk for brain tumors among cell phone users, and inadequate evidence for other types of cancer."
"Bluetooth devices use RF radiation in a similar wavelength range as those used for cell phones."
