Cancer cells have a complex interaction with the cells of the immune system that are present in the stroma. The immune cells have the potential to destroy the tumor if it is recognized as aberrant tissue. Which one of the following statements correctly describes an interaction between cancer cells and the immune cells of the stroma? A.  Tumors stimulate formation of new blood vessels—angiogenesis—promoting tumor survival. B.  The tumor establishes an immunosuppressive environment by blocking white-cell activation. C.  Tumors invoke an inflammatory reaction that blocks entry of immune cells into the stroma. D.  Immune cells block tumor growth by providing signals that inhibit cancer cell proliferation.
