Brief summary:
This randomized phase II trial studies how well docosahexaenoic acid works in preventing recurrence in breast cancer survivors. Docosahexaenoic acid supplement may prevent recurrence in breast cancer survivors.

Detailed description:
PRIMARY OBJECTIVES:

I. To determine whether treatment with docosahexaenoic acid (DHA) for 12 weeks at 1000 mg twice daily as compared to placebo reduces normal breast tissue levels of tumor necrosis factor-alpha (TNF-alpha) in overweight and obese patients with a history of stage I-III invasive breast cancer, ductal carcinoma in situ (DCIS), Paget's disease, lobular carcinoma in situ (LCIS), or proliferative benign breast disease.

SECONDARY OBJECTIVES:

I. To investigate the effect of DHA at 1000 mg twice daily on tissue biomarkers

* Change from the baseline in cyclooxygenase-2 (COX-2)/interleukin-1-beta (IL-1beta)/aromatase measured by quantitative real-time polymerase chain reaction (PCR).
* Change from the baseline in crown-like structures of the breast (CLS-B) measured by immunohistochemical techniques for cluster of differentiation (CD)68.
* Change from baseline in CLS-B index determined as follows: (\[number of slides with evidence of at least one CLS-B\]/\[total number of slides examined\]).
* Change from baseline in CLS-B/cm\^2 defined as the number of CLS-B/cm\^2. II. Evaluate age as a predictor of CLS-B and inflammatory biomarkers (TNF-alpha/COX-2/IL-1beta) at baseline and over the time of treatment.

III. Evaluate red blood cell (RBC) fatty acid level as a surrogate of compliance.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive docosahexaenoic acid orally (PO) twice daily (BID) for 12 weeks.

ARM II: Patients receive placebo PO BID for 12 weeks.

Arms:
arm 1: Docosahexaenoic Acid orally twice a day (PO BID) for 12 weeks. arm 2: Placebo orally twice a day (PO BID) for 12 weeks.

Interventions: intervention 1: Docosahexaenoic Acid intervention 2: Placebo
Intervention descriptions: intervention 1: Given PO intervention 2: Given PO
