1. Flaxseed
One of the most popular anti-breast cancer foods is flax seeds. The storehouse of Omega-3s, lignans, and fiber found in flaxseeds forms a protective layer against cancer cells that cause breast cancer. The flax seeds are available in the market as whole seeds, ground into powder or in the form of flaxseed oil. You can directly chew flaxseeds or incorporate them in meals you prepare. These seeds contain antioxidants, minerals, and dietary fibers, which will help prevent breast cancer.
