Question

Metastasis is when

• A. Cells divide
• B. A benign tumor is formed
• C. Malignant cells spread
• D. All of the above

Answer 1

The correct option is C

Malignant cells spread

Metastasis is the spread of cancer cells to new areas of the body (often by way of the lymphatic system or bloodstream). In metastasis, cancer cells break away from where they first formed (primary cancer), travel through the blood or lymph, and form new tumors (metastatic tumors) in other parts of the body.
