[Obesity and adipocytokines in breast cancer and benign breast disease].

Background: There is a relationship between obesity and the development of breast cancer; adipocytokines are among the mechanisms related.

Objective: To describe the impact of obesity in leptin, adiponectin, resistin and tumor necrosis factor-alpha (TNF-alpha) serum levels in women with breast cancer (BC) and benign breast disease (BBD).
