It has been known for decades that pregnancy, as well as breastfeeding, reduces the risk of developing breast cancer, especially pregnancies before the age of thirty. But so far, we didn’t know why.
Bacteria promote certain breast cancers
Canadian researchers have just understood what predisposes some women to develop cancer, or on the contrary, protects them. By analyzing tissue samples taken from women followed for either benign or cancerous tumors, and comparing them to samples taken from women without tumor, they discovered that the samples all contained several varieties of bacteria in varying amounts, such as in the intestinal flora.
And obviously, by digging a little, they realized that the samples of the women with a tumor contained significantly more staphylococci and bacteria. enterobacter Where bacillus. These bacteria are known for their ability to damage human DNA, and therefore, risk causing cancer.
Conversely, in samples taken from healthy women, the number of lactococci and streptococci was significantly higher.
Breast cancer: it would be possible to stimulate protective bacteria
Their conclusion is simple: not only are bacteria naturally present in the breasts, in all women, but the presence and number of some protects, or on the contrary, promotes the development of tumors. And according to them, it is possible to modify this distribution, by stimulating the presence of protective bacteria, in particular by taking probiotics which promote lactobacilli in particular.
For now, these are still only hypotheses, but it’s a safe bet that new studies will confirm, or deny, this promising path, which would prevent breast cancer and promote bacteria. can reduce the risk …
