One more study to frost the activists.

A Japanese study, published in the British Journal "Cancer" today, again refutes the claims by health activists that using cell phones will cause cancer. Researchers found that regular mobile phone users were not at an increased risk of three types of brain cancer. Although a few studies have shown an association between mobile phones and cancer, the majority found no link. The largest study to date, involving 420,000 people, showed no link with any type of cancer, even after 10 years of use.
