UCLA researchers determined that American women who incorporate fish oil capsules in their diet may reduce their risk of breast cancer. The study was based on the evidence that Asian women, who have one-third less breast cancer than American women, have a large amount of omega-3 in their breast tissues. Researchers hypothesize omega-3, which is found chiefly in fish, may protect breast tissue from cancer. American women taking fish oil capsules for just three months showed a significant increase of omega-3 in their breast tissue. The study will be published by the UCLA Jonsson Comprehensive Center in the Journal of the National Cancer Institute.
