Dichloroacetic acid is an experimental cancer drug. It is also referred to as dichloroacetate or DCA. It appears to kill cancer cells by changing the metabolism of cancer cells, causing programmed cell death of the cancer cells.
One article (1) looked into the effectiveness of dichloroacetic acid against cancer cells. It indicated that dichloroacetic acid did, in fact, cause cancer cell death in cancers such as cervical cancer, prostate cancer, endometrial cancer, brain cancer, colorectal cancer, and breast cancer.
The article indicated that dichloroacetic acid forces cancer cells away from their normal metabolism into glucose oxidation, which is the metabolism used by normal cells. It noted that dichloroacetic acid, while being effective against cancer, had many side effects when given to humans so that it may need to be used in natural substances, such as turmeric and broccoli, instead of giving the DCA in its purified form.
