A nurse is learning the difference between normal cells and benign tumor cells. What information does this include?

Rationale: A. Anaplasia is a key feature of abnormal cells, particularly cancer cells, where they lose differentiation and the specialized features of the parent cell, which can be a hallmark of malignancy. B. Benign tumor cells retain contact inhibition, meaning they stop growing when they touch other cells. Loss of contact inhibition is typical of malignant tumor cells, not benign ones. C. Benign tumors do not invade surrounding tissues; they grow as a well-defined, localized mass. In contrast, malignant tumors invade and destroy adjacent tissue. D. Benign tumors usually grow in the appropriate tissue of origin and do not metastasize. Abnormal growth in the wrong place or time is more characteristic of malignant cells.
