A large number of studies indicate that a growing part of cancers are influenced by obesity. In obese individuals, cancers are more frequent and more aggressive, especially for post-menopausal breast cancer. The pathophysiological mechanisms that underlie the relationship between obesity and breast cancer carcinogenesis are complex and associate both an increased inflammation and angiogenesis, and altered plasma levels of several growth factors and hormones including insulin, IGF-1, adiponectin, leptin, and oestrogens.More specifically, a sum of epidemiological, genetic, and experimental studies converge to suggest an anti-carcinogenic role for adiponectin. This could lead to the development of new therapeutic strategies through a modulation of the signaling of this adipose tissue-derived hormone.
