Brief summary: The study plans to find out whether Celebrex may be potentially useful to decrease inflammation in fat tissues and thereby lower the production of substances such as estrogens that may increase the risk of developing breast cancer and lead to a poor outcome of the disease.

Detailed description: This study seeks to examine how effective the celebrex may be in reducing inflammation, crown-like structures in fat tissue, the enzyme aromatase, PGE-M in the urine and estrogen in blood and urine. Volunteer subjects will be expected to stay in the hospital for about 2 weeks taking Celebrex for approximately 10 days while eating a diet similar to what they consumed before coming into the hospital for the study.
