Cellphones Do Not Increase Brain Cancer Risk

A 30-year study of just about everyone in Scandinavia has found no link between rising mobile use and rates of brain cancer. This is good news for chronic users of cellphones.

According to the new brief communication published online December 3 in the Journal of the National Cancer Institute, there was no substantial change in brain tumor incidence among adults 5 to 10 years after cell phone usage sharply increased.

About Brain Tumor
Brain tumors are the abnormal growth of brain cells that may be benign or metastatic. Brain tumors account for about 2.4% of all the tumor diagnosesandare most challenging due to their critically delicate location.

Although cell phone use has been proposed as a risk factor for brain tumors, a biological mechanism to explain this association is not known.

To reach the conclusion, Isabelle Deltour, Ph.D., of the Institute of Cancer Epidemiology, Danish Cancer Society, in Copenhagen, and colleagues analyzed annual incidence rates of glioma and meningioma among adults aged 20 to 79 years from Denmark, Finland, Norway, and Sweden.

Researchers identified 60,000 patients who were diagnosed with these types of brain tumors between 1974 and 2003.

Head injury or traumatic brain injury is a leading cause of disability among children and young adults that leads to varying degrees of physical and mental stability. Fortunately, it is also one of the preventable brain disorder.

The researchers found that incidence rates over this 30 year-period were stable, decreased, or continued a gradual increase that started before the introduction of cell phones. They also found no change in incidence trends in brain tumors from 1998 to 2003.

The authors did not assess cell phone usage at the individual level during this time period, only brain tumor incidence.

About Schizophrenia
Schizophrenia is a mental disorder characterized by symptoms of thought, behavior and social problems.

"Because of the high prevalence of mobile phone exposure in this population and worldwide, longer follow-up of time trends in brain tumor incidence rates are warranted," the authors write.
