De-Kun Li wants to change the conversation on cell phones and cancer. Li, a senior epidemiologist and veteran EMF researcher, believes that brain tumors have been getting too much attention at the expense of other types of cancer, notably colorectal cancer.

Efforts to reduce colon and rectal cancers have been a striking success story for those over 50 years old. Incidence among older Americans declined 32% between 2000 and 2013, due largely to better screening. But the story for young adults is very different. Those born around 1990 now face four times the risk of developing rectal cancer and twice the risk of colon cancer in their 20s, compared to those born around 1950, according to the American Cancer Society.

“No one can explain this apparent contradiction,” Li told Microwave News. Known risk factors for colorectal cancer include obesity, an unhealthy diet and lack of physical activity, but Li doesn’t think they can resolve the paradox.

The incidence of brain tumors in Australia did not increase between 2003 and 2013, according to a new analysis by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) and the Australian Centre for Electromagnetic Bioeffects Research (ACEBR). This means that there can be no link between the use of mobile phones and brain cancer, they claim. 

If such an association were true, “then the brain tumor rates would be higher than those that are observed,” states an ARPANSA press release that accompanies the new paper published in BMJ Open.

“People say mobile phones can cause cancer but our study showed this was not the case,” said ARPANSA’s Ken Karipidis, the lead author.

Others are skeptical. The work is incomplete and misleading —or worse, they say.
