The baking soda cancer hoax involves a false belief that because many cancers are white, they are caused by fungal infections. The solution, the theory follows, to ridding the body of tumors is to inject them with baking soda, explains Cancer Research UK, which notes the problems with this theory.
Not all cancer cells are white, asserts Cancer Research UK. Even if they were, there has been no scientific evidence to corroborate the claim that tumors are a reaction to a fungal infection. Additionally, the treatment suggested is not even recommended for fungal infections, because high doses of baking soda can have very negative effects.
