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.
