Can Cellphones Cause Cancer?


Radiation emitted from a mobile phones is “possibly carcinogenic” and may cause a certain type of brain cancer called glioma, says the International Agency for Research on Cancer or IARC, which is under the World Health Organization.

The international group of experts put radio-frequency electromagnetic fields, which are emitted from cellphones, microwaves, radar, radio, television, and wireless signals, in the same category as chloroform, coffee, DDT and lead.

“Possibly carcinogenic” is the third-highest rating by IARC. It is below “carcinogenic to humans” like tobacco and “probably carcinogenic” like diesel exhaust. However, experts say classifying radiation and other agents as “possibly carcinogenic” does not automatically mean they can cause cancer, and the finding should not alter people’s habits on cellphone.

Over the previous week, several scientists from various countries reviewed many existing studies, which include IARC’s Interphone study that claimed that over half an hour every day within 10 years period can increase the risk of having glioma by 40 percent.

However, the expert panel concluded that there was limited evidence that use of cellphone was linked to brain tumors and other types of cancer. Yet, World Health Organization warns people against frequent and lengthy use of mobile phones.

Although additional research is required, it is important to take practical measures that would reduce exposure to radiation such as use of hands-free devices, as well as texting, said Christopher Wild, director of IARC.

Also, children, teens and pregnant women should use cellphones as strictly as possible since they are at higher risk to absorb radiation, said head of the Rotary Cancer Institute Dr. GK Kath at AIIMS.
