Saturday April 6, 2013 (foodconsumer.org) -- A study in Antioxidants & Redox Signaling provides a bit more evidence suggesting that using mobile phones or cell phones in the U.S. can boost the risk of brain cancer.

The study led by Yaniv Hamzany from Petah Tiqva and Sackler Faculty of Medicine, Rabin Medical Center, Tel Aviv University in Tel Aviv, Israel and colleagues did not find a direction link between use of mobile phones and brain cancer. Instead, it finds that using mobile phones can induce oxidative stress which is linked to cancer.

Use of mobile phones has led to concerns regarding harmful effects of radiofrequency non-ionizing electromagnetic radiation on human tissue located lose to the ear, the authors say in their report.

In the past, industry-sponsored studies which considered often a less than 10 year exposure found no link between mobile phone use and the risk of brain cancer while other studies which considered a longer-than-10-year exposure found a significant association.

In the current study, researchers monitored 20 individuals who used mobile phones for a mean duration of 12.5 years and a mean use time of 30 hours per month and deaf individuals who did not use mobile phones as controls for salivary outcomes including secretion, oxidative damage indices, flow rate and composition.

The researchers found a significant increase in all salivary oxidative stress indices and a significant decrease in salivary flow, total protein, albumin, and amylase activity in mobile phone users, compared with controls.

Could use of mobile phones affect the brain as it does to salivary functionalities?

Dr. L. Hardell from University Hospital in Örebro, Sweden, probably the one and only brilliant epidemiologist who discovered a strong association between long-term use of mobile phones and elevated risk of brain cancer, published a new study in Neuroepidemiology that shows users of mobile phones and cordless phones had lower odds of survival from brain cancer.
