Whenever a cell becomes cancerous, our DNA sends it a signal to self-destruct. This is one of the most powerful safeguards we have in preventing cancer and it works the majority of the time. Unfortunately, it only takes one cancer cell capable of blocking this signal for a tumor to form. It is specifically those cells that are capable of overriding the self-destruct signal from the DNA that continue to grow and eventually form tumors. Ellagic acid reiterates the self-destruct signal in cancerous and precancerous cells.
