A new study has identified a potential link between a common oral bacterium associated with gum disease and the progression of breast cancer. Researchers found that Fusobacterium nucleatum, typically present in dental plaque, can travel to breast tumor sites. The bacterium appears to create a pro-inflammatory environment that may promote tumor growth and metastasis. The findings suggest that maintaining good oral health could have implications beyond dental care, potentially influencing cancer outcomes. Further research is needed to confirm the causal relationship and explore potential therapeutic interventions. Read the full article at: https://www.sciencedaily.com/releases/2026/03/260319044719.htm
