Can fluoride cause cancer?

Stacy Wiegman answered:According to most research as of 2010, fluoride does not cause cancer. It's true that at least one study, in animals, has found a link between fluoride and cancer. But dozens of other studies -- of people as well as animals -- show that fluoride does not increase your cancer risk. The U.S. Public Health Service and Centers for Disease Control and Prevention both say that fluoride is safe for you to consume.

According to the best available scientific evidence, there is no association between fluoridation and cancer. It is the single most effective public health measure to prevent tooth decay and has been named by the CDC as one of 10 great health achievements of the 20th century.
