Rates of thyroid cancer tripled since 1975 - public water utilities continue to poison us with water fluoridation

(NaturalNews) As scientists struggle to explain why thyroid cancer rates have more than tripled in the U.S. since the mid-1970s, nobody's addressing the elephant in the room that is artificial water fluoridation and the confirmed toxicity of fluoride chemicals when they enter the thyroid gland.

A study published last year attempted to explain away the thyroid cancer epidemic in the U.S. today, blaming it not on more actual cases of the disease, but rather on morediagnoses. The problem, say researchers from Dartmouth University, is that thyroid cancer is supposedly overdiagnosed and overtreated.

"The incidence of thyroid cancer is at epidemic proportions, but it doesn't look like an epidemic of disease," believes Dr. H. Gilbert Welch, a professor of medicine at the Dartmouth Institute for Health Policy and Clinical Practice. "[I]t looks like an epidemic of diagnosis," he's quoted as saying by HealthDay News.

It's a plausible hypothesis, actually: Just like with prostate cancer, testing regimens for thyroid cancer oftentimes pick up benign cancers that never would have developed into anything serious. Meanwhile, many of those diagnosed undergo invasive procedures, such as having their thyroids completely removed, that were never even necessary.

"This means that a lot of people are having their thyroids removed for a cancer that was never going to bother them," said Dr. Welch, suggesting that, as more people become aware of thyroid cancer and have their necks examined to look for problems, they're being misdiagnosed.

Multiple studies dating back to the 1970s link fluoride exposure to thyroid and other cancers

But what about the fluoride connection? Sure, some folks are being misdiagnosed as this study suggests, but it's surely not misdiagnosis that's primarily responsible for the more than 300% rise in thyroid cancer rates over the past 40 years. So what is it?

A study published just this year showed that fluoride ingestion is directly associated with rising rates of underactive thyroid, or hypothyroidism. Published in the Journal of Epidemiology & Community Health, the paper "raises questions about the safety of community fluoridation," to quote the words of one of its authors...........
