Independent Study Concludes Cell Phones can Cause Brain Tumors

Despite debate, the newest independent studies suggest cell phone use is not safe. Using current standards of exposure to microwaves, an independent study shows the risk of brain tumors from wireless phones is double that of non-users over ten years.

Scientists are calling for a revision of standards to lower the chances of brain tumors from wireless microwave exposure that include malignant gliomas and benign acoustic neuromas.

In a series of independent studies, researchers found flaws in past studies, as well as possible bias that led to previous conclusions. The newest studies finds a substantial risk of tumors of the brain that increases in proportion to the number of hours spent talking on a cell phone.

Eleven past studies funded by wireless companies, called the Interphone studies were inconclusive. The current independent study led by R.B. Dubey of Apeejay College of Engineering, Sohna, Gurgaon, India concludes “that the current standard of exposure to microwave during mobile phone use is not safe for long-term exposure and needs to be revised."

Cell Phone Waves Penetrate the Skull

No one is certain why cells phones increase brain cancer risk, but past studies have shown microwave from wireless phones can penetrate the skull up to 2 inches and much deeper in children, something that raises concern.

The researchers write, "Long-term cell phone usage can approximately double the risk of developing a glioma or acoustic neuroma in the more exposed brain hemisphere,”, or the side the user holds the phone. The conclusion is also consistent with the Interphone studies. The current study is based on a pooled analysis of existing studies.

The best evidence to date, according to the independent research, is that brain cancer is a risk associated with frequent cell phone use. The risk over a ten year period is twice that of non-mobile phone users.

Until definitive studies are available, recommendations include limiting wireless calls and keeping them short, text instead of talk, wear an “air tube” versus wire headset and limit children’s exposure to cell phones.

Based on the findings, researchers are asking for adoption of new cell phones and other technology, in addition to asking the government to revise standards for microwave exposure.

According to the authors, “...it is time for governments to mandate precautionary measures to protect their citizens." They note that children are among the heaviest cell phone users, with over 3 million people seemingly at risk for brain tumors from cell phone microwave exposure.
