Abstract：

Breast cancer is one of the most common tumors among women in the world, and it is also the main cause of cancer related death for women. The main cause of death is metastasis. With the development of tumor research and the progress of diagnostic technology, intestinal flora has been found to be related to the occurrence and development of breast cancer, and participate in the metastasis of breast cancer in the process of material metabolism, regulation of the immune system, chemotherapy, radiotherapy and the impact of traditional Chinese medicine treatment. This article reviewed the correlation and mechanism between intestinal flora and breast cancer metastasis, in order to guide clinical and scientific research work.
