Overview
Brief Summary
The overall objective of this clinical study is to determine the feasibility of breast CT for breast density assessment and association of CT-derived density measures with metabolic syndrome in overweight/obese Mexican-origin women in Southern Arizona. These evaluations will help support follow-up clinical research utilizing breast density acquired by breast CT as a surrogate endpoint biomarker to evaluate breast cancer preventive strategies. The long-term goal of these research efforts is to develop safe and effective preventive strategies to reduce obesity-associated breast cancer burden in our catchment area.

Outcomes
Primary Outcomes
Measurement of breast density
Time Frame: Baseline
To determine the feasibility of applying a novel clinical prototype of breast CT to assess breast density on non-compressed breasts. Feasibility will be evaluated by the proportion of unmeasurable breast density within our study population utilizing computerized tomography (CT) scan.
Secondary Outcomes
- Determine the association between metabolic syndrome and breast CT-derived density measures.(Two years)
- Comparison of CT-derived breast density measures versus the individual components of metabolic syndrome.(Two years)
