DCA, or dichloroacetate, is a small molecule that has been shown to be effective in the treatment of cancer. DCA is administered intravenously, and works by targeting cancer cells causing them to self-destruct. DCA is an alternative cancer treatment that has shown promise in clinical trials. Cancer cells are able to divide and grow unchecked because they have mutated forms of the protein p53. DCA can restore the function of p53, causing the cancer cells to die. DCA has been shown to be effective against a wide range of cancers, including breast, lung, and colon cancer. DCA is generally well-tolerated.
