近日, 一项研究发现,乌龙茶或许具有神秘的抗癌功效,它可以破坏乳腺癌细胞,而且喝乌龙茶多的人患乳腺癌的风险更低。

近日, 一项研究发现,乌龙茶或许具有神秘的抗癌功效,它可以破坏乳腺癌细胞,而且喝乌龙茶多的人患乳腺癌的风险更低。

尽管近年来乳腺癌的筛查和治疗技术取得了进步,但乳腺癌仍然是最常见的癌症之一,而且是导致女性死亡的第二大癌症。

因此,研究人员仍然在寻找更加有效的预防和治疗策略。此外,鉴于化疗的副作用,人们也迫切地需要非毒性的替代疗法。

在这种背景下,科学家们已经研究了绿茶对预防乳腺癌的潜在益处,他们发现了绿茶中存在某些具有抗癌作用的化合物。然而,几乎没有研究关注过其他的茶叶对乳腺癌的预防作用。

近日发表在《Anticancer Research》的这项研究关注了乌龙茶对预防乳腺癌的潜在益处。该研究由美国圣路易斯大学内科医学系的助理教授Chunfa Huang博士领导。

Huang及其团队测试了乌龙茶提取物对6种乳腺癌细胞系的影响,包括ER阳性、PR阳性、HER2阳性和三阴性乳腺癌细胞。

研究人员使用不同浓度的绿茶、乌龙茶、红茶和黑茶提取物作用于这些细胞。他们检测了这些癌细胞的生存能力以及DNA的损伤和分裂情况,还关注了细胞形态的其他变化。

绿茶和乌龙茶的提取物抑制了所有类型乳腺癌细胞的生长。相比之下,红茶和黑茶提取物则对这些细胞没有影响。

Huang和他的团队总结道:“乌龙茶与绿茶一样,可以诱导DNA损伤和分裂,对乳腺癌细胞生长、增殖和肿瘤形成具有抑制作用。它非常具有潜力成为针对乳腺癌的化学预防药物。”

此外,研究人员分析了我国福建省的年度癌症注册数据,结果发现,与全国平均水平相比,福建地区患乳腺癌的风险降低35%,死于这种疾病的风险降低38%。

他们还指出,与福建省的平均发病率相比,定期引用大量乌龙茶的人患乳腺癌的可能性降低25%,与全国平均水平相比,可能性降低50%,过早死亡的风险降低了68%。

Huang说:“乌龙茶消费量更高的地区发病率和死亡率较低,这表明乌龙茶具有抗癌特性。这些结果值得更深入与广泛的研究。”

Huang总结说:“根据我们的结果,乌龙茶与绿茶非常相似,它在抑制乳腺癌细胞生长、增殖和肿瘤形成方面起着重要的作用。”
