Warning over use of talcum powder due to possible link to cancer
警告：使用滑石粉可能会致癌
The World Health Organisation has sounded the alarm on talcum powder, suggesting a possible cancer link. Talc, a staple for preventing chafing and a long-time fixture in baby care routines, as well as a common product for athletes and countless women, is under scrutiny.
世界卫生组织已就滑石粉发出警告，暗示其可能与癌症存在关联。滑石粉是一种防止摩擦的必需品，长期以来一直是婴儿护理程序以及运动员和无数女性常用的产品，而现在它正受到审视。
Worries have surfaced about the potential connection between applying talc in underwear and ovarian cancer. The International Agency for Research on Cancer (IARC), part of the WHO, has recently concluded a review assessing the carcinogenic nature of talc.
人们开始担心在内裤上使用滑石粉与卵巢癌之间可能存在的联系。世界卫生组织旗下的国际癌症研究机构（IARC）最近完成了一项评估滑石粉致癌性的审查。
Extracted globally, talc is a mineral that poses exposure risks during its mining and refining. It's found in various consumer products including cosmetics, body powders, food items, drugs, and more.
滑石粉是一种在全球范围内开采的矿物，在开采和精炼过程中存在暴露风险。它存在于各种消费品中，包括化妆品、爽身粉、食品、药品等。
The WHO has issued a statement declaring: "After thoroughly reviewing the available scientific literature, the Working Group of 29 international experts classified talc as probably carcinogenic to humans (Group 2A) on the basis of a combination of limited evidence for cancer in humans (for ovarian cancer), sufficient evidence for cancer in experimental animals, and strong mechanistic evidence that talc exhibits key characteristics of carcinogens in human primary cells and experimental systems."
世界卫生组织发表声明称：“在全面审查了现有的科学文献后，由29名国际专家组成的工作组根据以下组合将滑石粉归类为可能对人类致癌的物质（2A类）：在人类中有限的癌症证据（针对卵巢癌）、在实验动物中充分的癌症证据，以及强有力的机制证据表明滑石粉在人类原代细胞和实验系统中表现出致癌物的关键特征。”
The Group 2A classification is the second highest level of certainty that a substance can cause cancer. Studies have consistently shown an uptick in ovarian cancer among individuals who reported using body powder in the perineal area.
2A类分类是确定某种物质可能致癌的第二高确定性水平。研究一致表明，在报告在会阴区域使用爽身粉的人群中，卵巢癌的发病率有所上升。
The WHO said: "A causal role for talc could not be fully established. An increased rate of ovarian cancer was also observed in studies looking at occupational exposure of women exposed to talc in the pulp and paper industry.
世卫组织表示：“无法完全确定滑石粉会导致卵巢癌。在研究造纸和纸浆工业中接触滑石粉的女性的职业暴露时，也观察到了卵巢癌发病率的上升。
However, confounding by co-exposure to asbestos could not be excluded, and the increased rate was based on small numbers of ovarian cancers in those occupational studies."
然而，不能排除同时接触石棉的混杂因素，而且职业研究中卵巢癌发病率的上升是基于少数病例。”
In lab tests, animals treated with talc saw a rise in malignant tumours in female subjects (adrenal medulla and lung) and both benign and malignant tumours in male rats (adrenal medulla).
在实验室测试中，用滑石粉处理过的动物中，雌性动物（肾上腺髓质和肺）的恶性肿瘤发病率上升，雄性大鼠（肾上腺髓质）的良性和恶性肿瘤发病率也有所上升。
苏格拉底有一句名言：我知我无知。说的是，当你认识到的东西越多就越发现自己无知。苏格拉底认为，人对于客观世界的认识是有限的，且不可能完全认识客观世界，并且不应对客观世界刨根究底。神对于世界的规划自有安排，若人一意孤行地探索世界和自然的奥秘，则最终将亵渎甚至触怒神明。正因为人对神所构建的世界不可能实现完全认知，因此那些宣称自己能够认识和改造世界的人，本身便是无知的代言。尽管苏格拉底的关于“ 我知我无知”的观念的解读，在现在看来有失客观科学。但至少苏格拉底告诫人们，人的认知是有限的，现有的知识甚至可能存在错误和疏漏。因此，无论任何时代，我们都必须对自己的无知加以认识并通过不懈的开拓，去更新甚至颠覆固有的知识结构。我们在求学之路上也要报以我知我不知的心态，才能走得更远、终有所成。最后，祝愿每一位考研学子都能顺利上岸！
