Brief Summary
The purpose of this research is to examine the effect of a broccoli sprout preparation on specific factors in breast tissue that are related to breast cancer risk and to assess whether sulforaphane a key component of broccoli sprouts increases the levels of protective enzymes in breast tissue. In addition, the investigators will also examine how acceptable the broccoli sprouts preparation is to the study participants.

Outcome Measures
Primary Outcomes (1)
Absolute Change in Mean Proliferative Rate Measured by Ki67%
Pathologists score the slides without knowledge of treatment assignment at the end of the study. All pre-post samples from one individual will be evaluated together. Quality control for these stains is performed routinely in the immunohistochemistry lab (using lymphoid tissue for Ki67). Initial scoring is performed where possible on a minimum of 3000 cells, by counting the number of positive cells divided by the total number of cells. DCIS lesions will be scored separately to adjacent normal tissue. The rationale for selecting Ki67 as a measure of cellular proliferation includes the robustness of the staining reaction, correlation with the S phase fraction of the cell cycle and mitotic index and that it can be successfully ascertained from core breast biopsies provided there is an adequate yield of epithelial cells. A negative value reflects a decrease in ki67 positive cells, therefore a decrease in cellular proliferation.

Study Arms (2)
Broccoli sprout extract
EXPERIMENTALPatients will be randomized to 14 day intervention of broccoli sprout extract and mango juice consisting of a dose of 100 µmols of sulforaphane dissolved in 150 mL mango juice once a day.
Mango juice
PLACEBO COMPARATORPatients will be randomized to 14 day intervention of 150 mL mango juice without broccoli sprout extract extract once a day.
