Brief Summary

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.

• Fatty acid profiles of breast adipose tissue

  0 and 3 months

Secondary Outcomes (1)

• Fatty acid profiles of serum, red blood cell membranes

  0 and 3 months

Study Arms (2)

Dietary fish (canned salmon, albacore)

EXPERIMENTAL

Fish products: Canned albacore and salmon will be provided at no cost to the patient. Supplies of tuna and salmon will be provided in quantities sufficient for one month of daily intake by the subject. If desired, a subject can request a sufficient amount to allow for preparation of a meal for the family or household at no more than two times per week. Labels or portions of labels from the cans will be collected at the monthly study visits, and canned supplies will be replenished monthly or at more frequent intervals if needed. Subjects will be allowed to keep unused cans.

Other: Dietary fish (canned salmon, albacore)

Lovaza-Omega 3 fatty acid capsules

EXPERIMENTAL

Lovaza capsules will be provided at no cost to the patient. Pill bottles will be provided to the patient, with the start date and number of pills recorded. The supplement will be provided in sufficient supply for one month at a time. Pill bottles will be collected at monthly follow-up visits, and any unused capsules will be documented and discarded as biohazardous waste.

Dietary Supplement: Lovaza-Omega 3 fatty acid capsules

Interventions

Lovaza-Omega 3 fatty acid capsules DIETARY_SUPPLEMENT

The study will require monthly visits at 0, 1, 2 and 3 months of study intervention. At each visit a fasting serum sample will be obtained, self-report diaries (adverse events, record of omega 3 supplement doses or fish servings taken/missed) will be collected, and pill count / labels from cans of fish will be recorded. Medications and supplements will be reviewed with participants at each monthly visit. At clinic visits at 0 and 3 months, a history and physical examination and breast adipose fine needle aspiration (FNA)will be performed.Omega 3 supplements will be dispensed in monthly amounts.

Dietary fish (canned salmon, albacore) OTHER

Participants randomized to dietary fish will be asked to incorporate fish in the form of canned albacore and salmon into their diets at four 6 oz servings per week for 3 months. Participants on the dietary fish arm of the study will receive recipes using canned salmon and/or albacore. Sufficient canned salmon/albacore will be available for subjects who wish to prepare a meal for the family/household. Dietary intake will be assessed via 3 day diet records (0 and 3 months) and food frequency questionnaires (0 and 3 months). Verbal and written instructions on how to keep diet records, with food measured or weighed, will be given.
