334. 癌症预防新策略

from 知为谁 · host 知为谁

这份来自《经济学人》的文章讨论了癌症预防的新兴科学方法,它挑战了癌症起源的传统观念。文章解释了携带癌症驱动突变的细胞在健康组织中普遍存在,但它们通常不会发展成肿瘤,因为周围健康的细胞会通过竞争来抑制它们。因此,一种有前景的癌症预防策略是鼓励这些健康细胞的生长,例如通过使用二甲双胍等药物来平衡细胞间的竞争。此外,研究还发现,慢性炎症而非仅仅是基因突变,是许多致癌物(如空气污染)促使这些“问题细胞”发展成恶性肿瘤的关键。这促使科学家考虑通过调节免疫系统来预防癌症,而非仅关注突变本身。内容来源:https://www.economist.com/science-and-technology/2025/09/02/scientists-are-discovering-a-powerful-new-way-to-prevent-cancer
