It’s a long-running medical mystery: Why have so many people under 50 in affluent countries been developing colorectal cancer in recent decades?

Something new is triggering a jump in what’s known as early-onset colon and rectal cancer (EOCRC). The rates have been going up for the last 20 years and no one knows why it’s happening. The usual risk factors for CRC —obesity, smoking, bad diet and lack of exercise— don’t fully explain the increase.

Five years ago, De-Kun Li, a senior epidemiologist at Kaiser Permanente in Oakland, CA, offered a new possibility: carrying a cell phone below the waist.

Senior European scientists are reporting that people living near cell phone towers show significant changes in their genetic makeup. This is the first time that chronic exposure to cell tower radiation has been linked to unrepairable genetic damage.

A team led by Wilhelm Mosgöller of the Medical University of Vienna and Igor Belyaev of the Slovak Academy of Sciences in Bratislava contend that years of low-dose RF exposure can increase the incidence of chromosomal aberrations. Such changes could lead to serious, though uncertain, health consequences, including cancer.

The new study is small —but provocative. It’s persuaded Mosgöller and Belyaev that they have identified a “biologically plausible mechanism” for how RF can cause cancer.
