Probiotics can prevent as well as reduce the number of tumors in the colon, liver and bladder.
Animal and human studies reveal that probiotics work their magic by stimulating immunity, reducing inflammation, and inhibiting of formation of tumor cells.
Probiotics interfere at different phases of the cancer evolution:
Initiation, in which toxic compounds or mutagens damage DNA or chromosomes, setting the stage for cancer activation.
What probiotics do: inactivate enzymes and bind to mutagens. Also they acidify the colon which is not as friendly to cancer.
Promotion, in which mucosa is irritated and cells proliferate.
Probiotics reduce inflammation and inhibit formation of pre-cancerous lesions.
Progression, the final stage when a previously benign polyp, for example, becomes a malignant tumor.
Microbes produce metabolites like organic acids, bacteriocins and peptides which interact all along the cancer highway from cellular proliferation, differentiation, apoptosis, inflammation, angiogenesis, and metastasis.
Along with a healthy diet– low in meat and fat and high in fiber–probiotics show great promise in cancer, a disease both capricious and devastating.
