Prompted by criticism from scientists and consumer groups, a US watchdog is set to revisit the potential risks from mobile phone usage.
Scientists and consumer groups have been criticizing the Federal Communications Commission (FCC), as they haven't revised mobile devices' standards since 1996.
Kerry Crofton, co-founder and executive director of Advisory Board Doctors for Safer Schools, said that the BioInitiative Report 2012 showed that an international group of scientists did a rigorous study to find a potential association between mobile phone use and brain cancer, as well safety concerns, and found that there were flaws in the FCC standards, Discovery News reported.
Current research has gone much more deeply into the potential risks.
David Gultekin, a researcher at the Memorial Sloan-Kettering Cancer Center in New York, has said that the relationship needs further study.
He said that what is known right now is that the cell phone radiation is heavily absorbed by brain tissue.
Gulaetkin asserted that the radiation also raised the temperature of the tissues.
We also know that absorption is not uniform throughout the brain, that there are hot spots that cause variations in energy inside the tissue."
Crofton said that brain cancer can take up to 20 - 30 years to develop.
