There are several hundred items classified as Group 2B, ranging from talc-based body powder to surgical implants made from nickel to titanium dioxide (used in paint, sunscreens and food coloring).

While this news may be scary, I still believe in the old adage of “moderation in everything” — try to limit your cell phone use and use a headset if possible, but don’t let this news make you go back to smoke signals and the telegraph.
