全世界与肥胖有关的癌症呈上升趋势,特别是年青成人,尽管死亡率没有增加。 Obesity-linked cancers are rising worldwide, especially in younger adults, though mortality hasn’t increased.

一项全球研究发现,从2003年到2017年,42个国家的年轻人和老年人肥胖致癌率不断上升,75%以上的国家甲状腺癌、直肠癌、乳腺癌和子宫内癌增加。 A global study finds rising rates of obesity-linked cancers in both younger and older adults across 42 countries from 2003 to 2017, with thyroid, colorectal, breast, and endometrial cancers increasing in over 75% of nations. 青壮年的直肠癌每年上升1.45%,甲状腺癌的增长速度最快,为每年3.57%。 Colorectal cancer rose 1.45% annually among younger adults, and thyroid cancer saw the fastest growth at 3.57% per year. 研究人员将肥胖、饮食和生活方式变化的趋势与肥胖、饮食和生活方式变化联系起来,但一项单独研究表明,过度诊断可能部分地解释了这一上升的原因,因为尽管自1992年以来诊断数翻了一番,但死亡率并没有上升。 Researchers link the trend to obesity, diet, and lifestyle changes, though a separate study suggests overdiagnosis may partly explain the rise, as mortality rates have not increased despite doubled diagnoses since 1992.
