A recent study in Sweden found wireless phones may be linked to a certain type of malignant brain cancer.
Researchers assessed a pool of people who had used cordless and cell phones over the last 25 years. These people were three times as likely to have glioma when compared to people who have used wireless phones for less than a year.
The study was published in the journal “Pathophysiology,” and is in direct contrast to the International Interphone study, which was partially funded by cell phone companies. That research did not find evidence linking cell phone use and brain cancer, but the new study from Sweden shows a correlation.
How often you talked on wireless devices also had an effect on the chances of developing cancer. Participants in the study who had talked the most on their wireless phones were twice as likely to develop glioma as those who had talked the least amount.
Even though the study found a correlation between brain cancer and cell phone use, the overall risk of developing the glioma is very low. Between 1995 and 2002, only 5 out of every 100,000 Europeans developed glioma, so tripling that number would still be considered low.
The research found no other connections with brain tumors other than glioma.
