世界癌症研究基金会的国际研究表明，英国、美国和荷兰50岁以下人群的多种癌症发病率正在以令人担忧的速度上升1。英国数据最为突出，50岁以下男性前列腺癌诊断自2001年以来增加了3.6倍，从每10万人1例上升至2023年的3.6例1。同期英国结肠癌诊断增加2.1倍，从每10万人3.9例升至8.4例，而子宫癌和肾癌发病率均翻倍至每10万人3.9例和3例1。美国的情况同样严峻，肾癌发病率从2000年的每10万人2.5例增至2023年的5.3例，增幅达2.1倍，结肠癌、子宫癌和胰腺癌的增长幅度超过50%，乳腺癌增长约20%1。
研究人员指出，肥胖、饮食不良和运动不足等生活方式因素是导致这一趋势的主要原因1。世界癌症研究基金会执行主任Giota Mitrou将这一发现称为"令人担忧的"1。约40%的癌症与可改变的风险因素相关1。为应对年轻成人结肠癌增长问题，伦敦国王学院已启动一项涉及25万人的新试验1。英国卫生社会保障部同时承诺到2035年实现一项目标，使四分之三诊断患者无癌症或带癌生存，预计可拯救32万条生命1。
An international study by the World Cancer Research Fund has identified a concerning surge in seven cancer types among people under 50 in the United Kingdom, United States, and Netherlands.1 In the UK, prostate cancer diagnoses among men under 50 have increased nearly fourfold since 2001, rising from 1 per 100,000 people to 3.6 per 100,000 by 2023, while colorectal, kidney, and uterine cancers have all doubled.1 In the US, kidney cancer rates increased 2.1-fold between 2000 and 2023, rising from 2.5 per 100,000 to 5.3 per 100,000 people, with colorectal, uterine, and pancreatic cancers growing by more than 50 percent and breast cancer rising by approximately 20 percent.1
Researchers attribute much of this acceleration to modifiable lifestyle factors, including obesity, poor diet quality, and physical inactivity, though they acknowledge that heightened diagnostic awareness has also contributed to rising detection rates.1 According to Giota Mitrou, executive director of the World Cancer Research Fund, the trends are "concerning," particularly given that roughly 40 percent of all cancers are linked to changeable risk factors.1 In response to these findings, King's College London has announced a new trial involving 250,000 participants to investigate colorectal cancer growth in younger adults.1 The UK Department of Health and Social Care has committed to a target of ensuring three-quarters of diagnosed cancer patients are cancer-free or living with cancer by 2035, a goal aimed at saving 320,000 lives.1
