A new study published in the Journal of the National Cancer Institute reports no association between cell phone use and brain tumors.
The accompanying commentary notes that,
In considering the need for future cell phone health research, it should be kept in mind that in addition to the negative epidemiological data, there is no known biologically plausible mechanism by which nonionizing radio waves of low energy can disrupt DNA and lead to cancer. The photoelectric effect is not a matter of opinion; radio frequency energy absorption cannot break DNA molecules, and carcinogenicity studies in animals are rather consistent in showing no increases in cancer following radio frequency energy absorption.
