“Fluoride causes more human cancer, and causes it faster, than any other chemical . . . more people have died in the last 30 years from cancer connected with fluoridation than all the military deaths in the entire history of the United States.”
—Dr. Dean Burk, Congressional Record, 21 July 1976.
Fluoridated Cities have higher rates of cancer.
In 1975 Dr Dean Burk, former head of the cytochemistry laboratory at the US National Cancer Institute, and John Yiamouyiannis, a biochemist, did an analysis of the cancer rates in the the ten largest fluoridated cities compared to the ten largest nonfluoridated cities in the USA from 1950 to 1970.
They selected cities that had similar cancer death rates for the preceding ten years i.e. 1940 to 1950. They found that while cancer rates had gone up slightly in the nonfluoridated cities, they had gone up a lot in the fluoridated cities. Watch this interview on a TV show in the Netherlands where Dr Dean Burk was able to explain their findings. Actual study can be found in Fluoride Journal.
These findings created a lot of controversy and two subsequent studies were published which showed no correlation and then further research found those studies to be flawed.
National Toxicology Program 1990
In 1990, the National Toxicology Program (NTP) released a report on fluoride’s carcinogenicity, which led to controversy and concerns over the “systematic downgrading” of cancers in the study. The report found a dose-dependent increase of a rare liver cancer (hepatocholangiocarcinoma) in male and female mice and a small but statistically significant dose-related increase in osteosarcomas in male rats but not in female rats.
Key Findings
- The 1990 study included the finding of a dose-dependent increase of a rare liver cancer (hepatocholangiocarcinoma) in male and female mice.
- A small but statistically significant dose-related increase in osteosarcomas was found in male rats but not in female rats.
“Fluoride is a carcinogen by any standard we use. I believe the EPA should act immediately to protect the public, not just on the cancer data, but on the evidence of bone fractures, arthritis, mutagenicity, and other effects.”
In 2006 a study was published in Cancer Causes and Controls. “Boys who drink water with levels of fluoride considered safe by federal guidelines are five times more likely to have a rare bone cancer than boys who drink unfluoridated water, according to a study by Harvard University scientists published in a peer-reviewed journal.
