在美国,每8位女性就有一位罹患乳癌,通常与年龄、遗传体质及环境变化有关。越来越多研究证明女性乳房组织里的细菌或许也是因素之一。20世纪60年代有研究发现,喂母乳的女性患乳癌的风险较低,之后的研究指出,原因可能是母乳有利于有益细菌的生长。加拿大西安大略大学微生物与免疫学教授瑞德就此继续深入研究。他比较两组女性乳房组织中的细菌DNA,分别是58名曾因良性或恶性肿瘤进行过乳房肿瘤
In the United States, one out of every eight women develops breast cancer, often related to age, genetic constitution, and environmental changes. More and more studies have shown that bacteria in female breast tissue may also be one of the factors. Studies in the 1960s found that breastfeeding women had a lower risk of breast cancer, and subsequent studies indicated that breast milk may be beneficial to beneficial bacterial growth. Reid, a professor of microbiology and immunology at the University of Western Ontario in Canada, continues to study this matter in depth. He compared bacterial DNA in two groups of female breast tissues, 58, respectively, who had breast tumors due to benign or malignant tumors
