Garlic May Help Block Some Cancers, Not All

Several studies have suggested a link between garlic intake and a reduced risk of cancer. To find out if garlic really has cancer-protective powers deserving of a labeling health claim, researchers from Korea evaluated 19 of the most well-controlled human studies. They found some limited evidence that garlic intake may play a role in reducing the risk of colon, prostate, esophageal, larynx, oral, ovary and kidney cancers. However, they found no credible evidence to support a link between garlic intake and a reduced risk of stomach, breast, lung or endometrial cancers.
