A hypothetical illustration of tumor metastasis being a systemic disease involving tissue inflammation-triggered secretion of eHsp90α. A primary tumor from the organ of its origin is unable to succeed on metastasis without chronic damage of a distant organ, such as IPF lung. The chronic inflammation of the damaged organ attracts and welcomes circulating tumor cells (CTCs) to their new home. Participation of tissue damage-triggered secretion of eHsp90α in tumor metastasis has been supported by recent studies.
