We have all seen them. The allegedly super busy executive, walking though the grocery store, putting beer, salad fixings and various sundries in a cart, all the while talking to himself. He’s on a bluetooth,of course, but you can’t help but be amused at watching someone seemingly talking to themselves.

Yes, the Bluetooth — that little handy device that fits inside your ear and makes your cell phone practically hands-free. Practically, because there isn’t a bluetooth out there that can always accurately understand the voice commands. But it’s pretty close to perfect technology.

Well, except for the whole cancer thing. For years, there have been discussions and concerns about cell phone and bluetooth devices causing cancer. Recently, the World Health Organization declared that cell phone could “possibly” increase the risk in brain cancer. And since a bluetooth isn’t just next to your ear, it’s IN your ear, it’s possible that it poses an even greater risk.

Sure, it’s possible to get cancer from your bluetooth device, it does emit radiation, which is proven to be cancer-causing. However, the Federal Comminication Commission and the Food and Drug Administration have determined the acceptable radiation levels for cell phones and bluetooth devices. The acceptable specific absorbtion rate (SAR) for a cell phone or bluetooth device is 1.6 watts per kilogram of body weight.

A bluetooth device has an SAR value of around 0.001 watts/kg. Can we say very little chance? Perhaps if you wore your bluetooth 24/7, it might be an issue. In 30 years. But for the typical user, it’s fine.

Now, I know that cancer is a scary topic, and many people are fearful of finding out they have it so they make sure they avoid as many cancer-causing issues as possible. But don’t you sometimes ask, “What doesn’t cause cancer?” Can you get cancer from eating a flame-broiled burger or steak? Studies suggest that you can. Can you get cancer from playing soccer in the sun for too long? Yep. What about the celebratory cigar? Definitely. So, it’s understandable why people would question the safety of taping a mini microwave to the side of one’s head. But still, the chances of you getting cancer from using a bluetooth headset are less than the chances of you having an accident if you are trying to talk on your cell phone, or worse, trying to text while you drive. So, to answer the original question, it hasn’t been proven that you can get cancer from using a bluetooth, but it hasn’t been disproven, either. However, if the Magic 8-Ball were answering the question, the triangle die in the blue liquid would most likely state, “More than likely, no.”

Or look at it this way: Even if you ate a steak with one hand, and a burger with the other, and while smoking a cigar you completed a scissor kick and won the soccer championship your chances of getting cancer are still extremely low.

But wouldn’t you pay to see that?
