A composition is prepared by extracting and isolating phytochemical fractions from plant matter for treatment of cancer and especially for breast, prostate, skin, colon, urinary and bladder cancer. The composition is enriched preferably with two or more different phytochemical fractions, namely, isoflavones, lignans, saponins and saponogenins, catechins, and phenolic acids. The two selected fractions are different from each other and are combined specifically to form a composition to treat cancer. Soy is the preferred source of these phytochemicals; however, other plants may also be used, such as wheat, psyllium, rice, oats, red clover, kudzu, alfalfa, flax, and cocoa. The composition may be delivered in an easy to use or consume form, such as creams, pills, tablets, capsules, dry powder, health bars, food ingredients and supplements, tablets, soft gels, and the like.
