Oral environment and cancer.

Area of Science:

• Oral Health
• Oncology
• Microbiology

Background:

• Cancer is the leading cause of death in Japan, with mortality expected to rise in an aging society.
• Lifestyle factors like smoking, diet, and alcohol significantly influence cancer risk.
• The oral environment plays a role in various systemic diseases and is a constant interface with external substances.

Purpose of the Study:

• To review recent findings on the association between the oral environment and cancer.
• To highlight the role of oral microbial flora and pathogens in cancer pathogenesis.

Main Methods:

• Literature review of recent scientific findings.
• Analysis of factors influencing the oral environment (local and systemic).

Main Results:

• The oral environment is increasingly recognized as a factor in cancer development.
• Commensal oral bacteria, Candida, human papilloma virus, and Epstein-Barr virus are implicated in cancer pathogenesis.
• Oral health is influenced by local factors (plaque, occlusion) and systemic factors (lifestyle, obesity, stress).

Conclusions:

• The oral environment, including its microbial composition, is significantly associated with cancer risk and development.
• Maintaining a healthy oral environment may be crucial for cancer prevention strategies.
