Can grape juice help to ward off breast cancer?
Aromatase converts androgen to estrogen. Aromatase is expressed at a higher level in breast cancer tissue than in benign tissue. In estrogen biosynthesis in tumor tissue has been shown to play a role in promoting tumor growth. Suppression of estrogen biosynthesis can be achieved by the prevention of aromatase expression in breast tumors or by the inhibition of aromatase activity. There are several natural products that inhibit aromatase, but grape juice certainly can rank as among the most tasty and beneficial.
