Heavy Cell Phone Use Linked to Oxidative Stress

July 29, 2013 — Scientists have long been worried about the possible harmful effects of regular cellular phone use, but studies so far have been largely inconclusive. Currently, radiofrequency electromagnetic fields, such as those produced by cell phones, are classified as possibly carcinogenic to humans (Group 2B) by the International Agency for Research on Cancer (IARC). A new Tel Aviv University study, though, may bring bad news.

Comparing heavy mobile phone users to non-users, they found that the saliva of heavy users showed indications of higher oxidative stress -- a process that damages all aspects of a human cell, including DNA -- through the development of toxic peroxide and free radicals. More importantly, it is considered a major risk factor for cancer.
