A nurse is teaching a group of nursing students about cancer treatment. Which statement by the student indicates an understanding of the characteristics of cancer cells?
a. "Cancer cells are characterized by unrestrained growth and division."
b. "Division of cancer cells is characteristically rapid."
c. "Malignant cells of solid tumors do not invade other tissues."
d. "Telomerase is an enzyme produced by cancer cells that promotes metastases."
ANS: A
Because malignant cells are unresponsive to the feedback mechanisms that regulate cellular proliferation in healthy tissue, they are characterized by unrestrained growth and division. Division of tumor cells is not necessarily rapid. Malignant cells of all types can metastasize. Telomerase is an enzyme that permits repeated division of cancer cells.
