Obesity, an excess accumulation of adipose tissue occurring in mammalians when caloric intake exceeds energy expenditure, is associated with an increased frequency and progression of several types of neoplastic diseases including postmenopausal breast cancer. Recent studies have suggested that obesity-related disruption of the energy homeostasis results in inflammation and alterations of adipokine signalling that may foster cancer initiation and progression. Moreover, two populations of human white adipose tissue (WAT) progenitors cooperate in breast cancer angiogenesis, growth and metastatic progression. This raises the issue of lipotransfer in patients undergoing plastic or reconstructive surgery.
