*2.5.14 Breast cancer*

Several studies have been conducted on animal and human models to check the effect of probiotics in breast cancer. Several in vitro studies have shown that probiotics are involved in reducing the tumor size and stopped the growth of tumour. In Human studies it was observed that the use of probiotic *Lactobacillus casei shirota* prevented the onset of breast cancer. Also the use of fermented dairy products such as yogurt and fermented milk was inversely linked with the onset of breast cancer. Probiotics can be used for both preventive and treatment purposes of breast cancer. However more studies are needed in order to confirm the safety and efficacy of probiotics in breast cancer [82].
