Final answer:
The term that refers to a cancerous growth is 'Malignant'. Malignant tumors can invade surrounding tissues and spread throughout the body, while benign tumors do not.
Step-by-step explanation:
The term that refers to a cancerous growth is C. Malignant. A malignant neoplasm, or malignant tumor, is characterized by uncontrolled cell growth, invasion of surrounding tissues, and sometimes metastasis, where the cancer cells spread to other locations in the body via lymph or blood. In contrast, a benign neoplasm, or benign tumor, usually remains localized, does not invade other tissues, and is not life-threatening, although it may be removed for comfort or because of the potential to become cancerous.
