Question

a cancerous growth that has spread from the site of origin, by way of the bloodstream, to invade a distant secondary location in the body. which of the following term best describes this cancer? a.) metastatic b.) malignant c.) tumor d.) benign

Explanation:

• Metastatic: Cancer that has spread from its original site to a distant part of the body via the bloodstream (or lymphatic system) is called metastatic cancer. This matches the description in the question.
• Malignant: While malignant tumors are cancerous, the term itself does not specifically imply spread (metastasis). A malignant tumor could be localized (not yet spread).
• Tumor: A tumor is just an abnormal mass of tissue. It can be benign (non - cancerous) or malignant (cancerous). The term “tumor” does not convey the idea of spread.
• Benign: Benign tumors are non - cancerous. They do not invade nearby tissues or spread to other parts of the body.

Answer:

A. Metastatic
