Despite what recently published on the Eur J Intern Med. by Bitzur et al., who did not found a significant correlation between obesity and the incidence of cancer in a population of mostly Jewish males, admitting themselves several limitations of their study, evidence of a relationship between obesity and enhanced cancer risk has been increasingly accumulating. Indeed, there are clear epidemiological findings linking obesity to the incidence and worst prognosis of different tumors [1]. This prompted us to introduce in the scientific terminology the new term “adiponcosis”, derived from the fusion of the words “adiposis” and “oncosis”, that is rapidly spreading in the international science community [2].
