Blood-borne cancerous cells have recently spread from a woman's primary tumor in her pancreas to her bones. what components of the woman's immune system are likely to be directly involved in the attempt to eradicate the potential metastasis?

T lymphocytes, macrophages, natural killer cells and B cells.

Explanation:

Cancer may be defined as the uncontrolled division of the cell and these cells loses the property of apoptosis. Two main types of tumor are malignant tumor and benign tumor.

Blood borne cancer cells known as leukemia. The immune cells help to destroy the cancer cells. T lymphocytes kill the cancer cells by activating the B cells. These B cells produce specific antibodies to kill the cells. Macrophages phagocytose  the cancer cells direct and natural killer kill the cells by antibody dependent cell mediated cytotoxicity.

Thus, the answer is  T lymphocytes, macrophages, natural killer cells and B cells.
