Vitals – Dental X-rays can double brain tumor risk, study finds.

In a bizarre twist, the researchers who discovered the risk increase back pedaled even as they announced their findings.  They talked about “recall bias” of patients who do have tumors (they are more likely to have thought back to all those dental x-rays and thought…mmmm….I wonder?)and don’t want people to panic.

They also went out of their way to say that this particular brain cancer isn’t actually that bad.  (Compared to what?  A puppy?  Or a grizzly bear?)

Here’s a tip from the rest of us.  If you don’t want us to panic, don’t tell us that dental x-rays double our risk of brain cancer.

But of course they do.  Radiation increases cancer risk.  All radiation.  So when you get your head irradiated every year, your chances of getting cancer go from .000001 to .00001 percent.  It’s still small, but it’s significant over time.

Mmmm… Cancer-in-a-can.  Can I get mine supersized?

Is it all hoopla?  Nope,  this is a nasty chemical.

Abstract

Research on acrylamide has been going on for the last four decades. However, its presence in carbohydrate-rich and high temperature processed foods was confirmed in 2002, after which a significant progress in this field has been made. A number of studies were conducted to explore the mechanism of its formation in carbohydrate-rich foods. Carbohydrate, protein, and fat are the main constituents of food, which are mainly responsible for the formation of acrylamide, and thus, a number of investigations were carried out to reduce its quantity in food. Moreover, various studies regarding carcinogenic and neurotoxic effects of acrylamide on animal models suggested that acrylamide can produce tumor in the thyroid gland, testes, mammary gland, lungs, clitoral gland, brain, and also enhance mutation, a step to cancer. Therefore, this review addresses the studies conducted since recently on the toxicological effects, formation mechanism and reduction of the formation of acrylamide in snack foods.
