Dietary Fish and Omega 3 Fatty Acids for Breast Cancer Prevention

Completed · Phase 1

Conditions studied: Breast Cancer

In brief

Research studies show that the type of fat in the diet may affect breast cancer risk. Fish oil and fish contain increased amounts of omega 3 fatty acids which appear to stop or slow down the growth and development of breast cancer cells in laboratory studies of mice and breast cancer cells. The use of omega 3 fatty acids to reduce the risk of breast cancer development in humans has not been adequately studied. Eating fish or taking fish oil may increase the amount of omega 3 in the breast, which may lower one's risk of breast cancer development. Persons in this study with do one of the following: (1) take two capsules daily of omega 3 fatty acid supplements, or (2) eat several servings of canned salmon / tuna per week for a total of three months. Amounts of omega 3 fatty acids in the body's tissues will be measured by blood tests and a small sample of breast fat as obtained by a fine needle aspiration. This study is supported by funding from the National Fisheries Institute, Food Innovation Center of The Ohio State University, and The Ohio State University Comprehensive Cancer Center.
