 This study examined the breast microbiome of male and female patients, finding that the male breast cancer microbiome differs from the female breast cancer microbiome. The researchers found that the male breast cancer microbiome has a greater abundance of bacteria belonging to the phylum Tenericutes, which may play a role in cancer development. Additionally, they observed that the male breast cancer microbiome is more similar to the microbiome of non-cancerous tissue compared to the female breast cancer microbiome, suggesting that the male breast cancer microbiome may be associated with better prognosis. This study provides important insight into the role of the microbiome in male breast cancer and highlights the need for further research into this area.
