Primary outcomePrimary: PUFA Levels in Normal and Metastatic Breast Tissue — 60.986; 72.762; 3.232; 3.505 ug/ml
Summary
This phase II clinical trial studies how well omega-3 fatty acid works in treating patients with stage I-III breast cancer. Studying samples of tissue and blood in the laboratory from breast cancer patients receiving omega-3 fatty acid may help doctors learn more about the effects of omega-3 fatty acid on tumor cells.

Eligibility Criteria
Inclusion Criteria

- Breast surgery (lumpectomy or mastectomy) is planned for at least 7 days from the day of enrollment
- Ability to understand and the willingness to sign an Institutional Review Board (IRB)-approved written informed consent document
- Tumor measures at least 1 centimeter on imaging or physical exam
Exclusion Criteria
- Any patient with surgery scheduled < 7days after biopsy
- Patients who are unable to refrain from the use of any NSAID or full-dose acetylsalicylic acid (ASA)-containing NSAID while taking study drug
- Patients who will receive neoadjuvant chemotherapy are not eligible
