Study: Daily consumption of yoghurt may reduce risk of breast cancer
The researchers believe these bacteria in the breast may be protective since earlier studies had reported that each year of breast feeding reduced the risk of breast cancer by nearly 5 per cent. A similar effect seen in yoghurt, the scientists said, may be due to the displacement of harmful bacteria by beneficial bacteria. "The stem cells which divide to replenish the lining of the breast ducts are influenced by the microflora, and certain components of the microflora have been shown in other organs, such as the colon and stomach, to increase the risk of cancer development," the researchers noted.
"Therefore a similar scenario is likely to be occurring in the breast, whereby resident microflora impact on stem cell division and influence cancer risk," they concluded.
