Cancer is the second leading cause of death from non-communicable diseases in the world.¹ In 2015, there were 17·5 million new cases of cancer and 8·7 million cancer-related deaths, with 208·3 million disability-adjusted life-years.² Cancer incidence is expected to continue to increase, partly due to changes in the prevalence of risk factors such as obesity, diabetes, and other lifestyle factors. Obesity, defined as body-mass index (BMI) of 30 kg/m² or more, has become increasingly common in all age groups and every country over the past few decades, irrespective of the country's sociodemographic status or region.

糖尿病和肥胖：癌症的重担

癌症是世界上非传染性疾病造成的第二大死亡原因。¹ 2015年，癌症新发病例为17·500万，癌症相关死亡为8·700万，经残疾调整后的生命年为208·300万。²癌症发病率预计将继续增加，部分原因是肥胖，糖尿病和其他生活方式因素等危险因素的患病率发生变化。肥胖定义为30 kg / m ²或更高的身体质量指数（BMI），在过去的几十年中，无论该国家的社会人口统计学状况或地区如何，肥胖在所有年龄组和每个国家中都变得越来越普遍。
