A Japanese study came to the same conclusion as others did that exposure to fluoride increases cancer risk. This study published in Journal of Epidemiology finds people with high intake of fluoride in their tap water had higher risk of uterine cancer death. The association was significant even after adjusting for all other potential con-founders.
Previous lab studies show that rats with high oral intake of fluoride have high risk of bone cancer. This elevated bone cancer risk has been also found in boys who have high intake of fluoride.
In humans, occupational fluoride exposure has been known to cause skeletal fluorosis and fluoride exposed workers were at high risk of respiratory cancers.
Another study study published in 1992 linked occupational fluoride exposure to bladder cancer. The study of 425 men and 97 women found that fluoride exposure increased risk of bladder cancer, lung cancer, laryngeal cancer and violent deaths.
Cancer Incidence and Mortality in Workers Exposed to Fluoride Philippe Grandjean Jørgen H. Olsen Ole Møller Jensen Knud Juel JNCI: Journal of the National Cancer Institute, Volume 84, Issue 24, 16 December 1992, Pages 1903–1909, https://doi.org/10.1093/jnci/84.24.1903

Dr. Dean Burk, former director of the U.S. National Cancer Institute claimed in a video released in 1972 that the cancer incidence drastically increased in cities where drinking water is fluoridated while other cities where tap water is not fluoridated only slightly increased.
The public is largely unaware of this cancer risk from fluoride. It is well known that fluoridated drinking water lowers children’s IQ.
Fluoride once added to drinking water is not easy to take out. Only a reverse osmosis filtering system can filter out fluoride.
