Eating Yoghurt daily lowers the risk of Breast cancer in women, suggests a new study, conducted by researchers of American society for microbiology
Taking probiotics daily will help increase the proportion of gut bacteria in the breast, protecting from the cancer risk. “The Lactobacillus and Streptococcus, considered to be health-promoting bacteria were found in the healthy breasts than in cancerous ones. Since both these groups have anticarcinogenic properties, our study raised the subject that Should women who are at risk of breast cancer take probiotic lactobacilli to increase the beneficial bacteria in the breast?,” said Dr Gregor Reid, the professor of microbiology, immunology and surgery at the Western University in Ontario, Canada
On the contrary, women with Breast Cancer were found to have the increased levels of Escherichia coli and Staphylococcus epidermidis, harmful bacteria that can provoke double-stranded breaks in DNA in HeLa cells. The Double-strand breaks are caused due to the genotoxins, reactive oxygen species and ionising radiation, the researchers added. The repair mechanism for the double-stranded breaks is error-prone leading to cancer development.
In addition, the natural killer cells are crucial in managing the tumor growth and a low level of these immune cells are linked to the risks of breast cancer. The Streptococcus thermophilus induces the anti-oxidants that counteract the reactive oxygen species, which can cause DNA damage, and thus, cancer.
Researchers found that the increased intake of Yoghurt and other probiotics protects women against breast cancer. Antibiotics targeting bacteria that abet cancer might be the other option for recovering from breast cancer, Reid added.
In the study published in the journal Applied and Environmental Microbiology, the researchers obtained breast tissues from 58 women who were undergoing lumpectomies or mastectomies for either benign (13 women) or cancerous (45 women) tumours, and from 23 healthy women, who had undergone breast reductions or enhancements.
The team found that women diagnosed with breast cancer had elevated levels of Escherichia coli and Staphylococcus epidermidis, while women with healthy breasts have the Health-promoting bacteria Lactobacillus and Streptococcus (lactic acid bacteria)
“Besides fighting cancer directly, it might be possible to increase the abundance of beneficial bacteria at the expense of harmful ones, through probiotics,” added Reid.
