A new study conducted by Swedish researchers has found that people who talk on mobile or cordless phones for over a period of 25 years face an increased risk of brain cancer compared to people who have talked on these phones for less than a year.
The study by Dr Lennart Hardell, an oncologist from University Hospital in Orebro, Sweden, and his colleague Michael Carlberg "matched 1,380 patients with malignant brain tumors to people without such tumors and compared their wireless phone use," Reuters reported.
AdvertisementThe researchers found that using wireless phones for 20 to 25 years put people at two times the risk of developing the malignant brain tumor glioma as compared to those who used the phones for less than a year. The risk increased by three times in people who used cell and cordless phones for more than 25 years.
Dr Hardell though said it was hard to make any formal recommendation over cell phone use, "It's hard to make formal recommendations because the data is lacking. It's not smoking and lung cancer because it's not proven,:" he stressed.
The study is reported in the journal Pathophysiology.
