Anti-inflammatory drugs and antibiotics alter the risk of breast cancer in women, but roles for bacteria and inflammation in breast malignancies are poorly understood. A recent study in mice suggests that intestinal bacteria can trigger mammary carcinoma. The mechanisms involved in this effect suggest that dysregulated host immune responses to enteric bacteria can influence the development of extraintestinal cancers, highlighting the opportunities for prevention and treatment aimed at promoting intestinal homeostasis.

Interesting post

Thank you

IBS etc inflamatory conditions are probably an indicator of poor bowel / intestinal function, which could I suppose result in bacterial imbalances, plus leaky cell walls....

There was a previous series of posts on H-Pylori bacteria and possible cancer links.
