前々から、体重過多は発がんリスクが高いことが警告されてきていましたが、2015年3月2日、米国臨床腫瘍学会（ASCO）から、がんになりやすさでは、まもなく“肥満”が”たばこ”をおさえて、第１のリスクファクターになるだろうとのニュースが配信されました。
肥満者は、体内のどこかで慢性炎症を起こしており、炎症が発がんの高いリスクファクターであるためとのことです。
配信されたニュース原文は以下です。「あなたは大丈夫ですか？」

ASCO Finds Obesity Likely To Become Top Risk Factor For Cancer.
Dr. Seun Sowemimo, a board-certified bariatric surgeon and obesity expert at CentraState Medical Center in Freehold, NJ, and Dr. Mary Martucci, a board-certified general surgeon and breast surgical oncologist, and medical director of The Star and Barry Tobias Women’s Health Center at CentraState Medical Center, write at LiveScience (3/1, 396K) pointing out that an American Society of Clinical Oncology (ASCO) report found that “obesity will soon become the number one risk factor for cancer.” In response, ASCO is calling for “immediate and substantive increases in weight control education, research and advocacy to raise public awareness” of the risk of cancer connected to obesity. In general, obesity may “cause chronic inflammation,” which can lead to “increasing production of the hormone estrogen,” which “has been shown to cause breast cancer tumors.”
