tumor microenvironment
The cellular and molecular environment surrounding cancer cells, including immune cells, blood vessels, and supportive tissue.
Full Definition
The tumor microenvironment encompasses all non-malignant cells, blood vessels, immune cells, and extracellular matrix components that surround and interact with cancer cells. This complex ecosystem plays a crucial role in tumor growth, invasion, metastasis, and response to treatment. Understanding the tumor microenvironment has led to new therapeutic approaches, including immunotherapy and anti-angiogenic treatments. In surgical oncology, characteristics of the tumor microenvironment influence surgical planning, predict treatment response, and guide adjuvant therapy decisions.
