Higher Oxidative Stress Levels in Saliva of Heavy Cellphone UsersFor a considerable length of time, scientists have been trying to understand, and come up with the negative consequences of regular mobile phone usage on health, but all studies done uptill now have failed to give some solid results. At present, cell phones are believed to be a potential carcinogen, according to International  Agency for Research on Cancer (IARC).

Dr. Yaniv Hamzanay of Tel Aviv University’s Sackler Faculty of Medicine at Tel Aviv University and the Otolaryngology Head and Nick Surgery Department at the Rabin Medical Center looked into the possible link between cancer rates and mobile phone usage by examining the saliva of the mobile phone users. The rationale for it was that when in use, the cell phone is positioned near the salivary glands. To develop the link, Dr. Yaniv along with Profs. Raphael Feinmesser, Thomas Shpitzer,  Dr. Gideon Bahar, Prof. Rafi Nagler and Dr. Moshe Gavish of the Technion in Haifa came up with a hypothesis that saliva can be linked with developing cancer.

It was discovered that the saliva of people with more frequent cell phone use had higher oxidative stress in contrast to those who used their mobiles less often. Higher oxidative stress is a major contributor of cancer.The saliva of 20 heavy-users was observed, who spent atleast 8 hours a month speaking on their mobile phones. According to Dr. Hamzany, a larger number of participants spent around 30 to 40 hours a month talking on their phone. The saliva sample of these people was cross examined with a control group consisting of deaf people. They did not use a cell phone or even if they did, it was solely with the purpose of sending messages and performing other non-spoken activities. The heavy-users of cell phone were found to have higher levels of salivary oxidative stress than the control group.

Dr. Hamzany believes that tumors are developed due to the damage caused by oxidative stress linked with cellular and genetic mutation.

This research explains the effect of mobile phone usage, and demonstrates more clearly the impact of radio frequency non-ionizing electromagnetic radiation on the tissue near the ear. The findings of the study shed some light on the long term effect of the use of mobile phones, if not produce a valid ’cause and effect’ link. Future research can be based on the observation of saliva before using a cell phone and after using it for a few minutes. This will help the researcher see if some movement is created in the molecules which shows oxidative stress.

This is not the first research that has been carried out linking cancer with mobiles. The National Cancer Institute has also recognized the effect of radio frequency emitted by mobile phones on the growing risk of cancer. An unbelievable figure of 6 billion constitutes those people who have more access to cell phones than to toilets and this number is going to grow even higher than the total population of the world by next year.

It has been suggested that policy regarding cell phones should undergo a revision by the Federal Communications Commission. According to Discovery News reports, no changes in this policy have been made since 1996.

“There were very few cell phones in service back in 1996, and now, by some estimates, there are 5 billion globally,” Kerry Crofton, co-founder and executive director of Advisory Board Doctors for Safer Schools, said. “The other concern is that the standards were based only on testing a 200-pound male mannequin, but the standards do not apply to more sensitive groups, such as children, pregnant women and teens. It took a hundred years for regulators to respond to that crisis, but the threat from not just cell phones, but WiFi networks and cell towers is immediate and widespread,” she said.
