Could carrots and sweet potatoes help fight breast cancer?

A nutrient in carrots and sweet potatoes may prove to be a vital weapon against breast cancer in early stages of the disease, research suggests.

Retinoic acid, a vitamin A derivative, also rejuvenates the skin and a weak version of it is used in anti-wrinkle face creams. The chemical affects cell growth, proliferation and survival. So far, studies of its potential as a cancer therapy have proved inconclusive.

Now a new laboratory study has shown that retinoic acid reverses early changes in cells that lead to breast cancer. However, it is ineffective once a certain stage of cancer development has been passed.
