The intake of probiotics can help increase the proportion of beneficial bacteria in the chest and therefore help prevent the risk of breast cancer.
The results showed that Lactobacillus and Streptococcus, considered health-promoting bacteria were more prevalent than in healthy breast cancer. Both groups have anticancer properties.
Therefore, “our work raises the question that should make women, especially those at risk for breast cancer, taking lactobacillus probiotics to increase the proportion of beneficial bacteria in the chest?” Gregor said Reid, a professor at Western University in Canada
on the other hand, women with breast cancer also showed elevated levels of Escherichia coli and Staphylococcus epidermidis -. harmful bacteria ‘- is known to induce double-strand breaks in DNA in HeLa cells (cultured human cells).
“double strand breaks are the most damaging type of DNA damage and are caused by Genotoxins, reactive oxygen species and ionizing radiation,” the researchers said.
repair mechanism of double strand breaks is highly error prone and these errors can lead to cancer.
In addition, natural killer cells are essential for the control of tumor growth and a low level of these immune cells is associated with a higher incidence of breast cancer.
Streptococcus thermophilus produces antioxidants that neutralize reactive oxygen species, which can cause DNA damage, and therefore cancer.
The study, published in the journal Applied and Environmental Microbiology, may ultimately lead to the use of probiotics to protect women against breast cancer.
antibiotics targeted bacteria that instigate cancer could be another option to improve the management of breast cancer, Reid said.
in the study, the team obtained the breast tissue of 58 women who underwent partial mastectomies or mastectomies for benign (13 women) or cancerous (45 women) tumors and 23 healthy women who they had undergone breast reductions or enhancements.
DNA sequencing was used to identify bacteria from tissues and crop to confirm living organisms.
