Leveraging Microorganisms to Combat Skin Cancer.

Skin cancer, including melanoma and non-melanoma types, presents a significant and growing global health challenge due to its increasing incidence and mortality rates. While conventional treatments such as surgical excision, immunotherapy, and targeted therapies are well-established, microorganism-based approaches represent an innovative and promising alternative. These therapies employ live, genetically engineered, or commensal bacteria, viral vectors, or bacterial components to achieve various therapeutic mechanisms, including tumor targeting, immune system modulation, vascular disruption, competitive exclusion, drug delivery, and direct oncolysis. Despite their potential, these approaches require further investigation to address safety concerns, optimize treatment protocols, and gain a comprehensive understanding of their long-term outcomes.
