What if a substance was found that normalizes out-of-control cell growth? The result could be a way to treat and prevent cancer. And a new study offers hope that discovery may have already been made. Scientists from the University of Chicago have just published groundbreaking research in the journal Cell which concludes a powerful compound exists that can restore a healthy balance to cell processes. It's not a new chemotherapy agent or drug but one derived from nature -- retinoic acid, a derivative of vitamin A.
According to the American Cancer Society, estrogen fuels the growth of two out of three breast cancers. The female hormone can spur on cancer by altering the expression of certain genes, resulting in breast cells that become malignant and proliferate. The University of Chicago study found that retinoic acid can also alter these same estrogen-sensitive genes. But instead of causing cells to grow without restraint, a hallmark of cancer, retinoic acid restored normal balance to the cells and inhibited their growth.
