Question

Which is cancerous tumour?

• A. Benign tumour
• B. Malignant tumour
• C. Lipoma
• D. All of the above

Answer 1

Answer: (B)

Malignant tumour

Benign tumour is the mass of cells (tumor) that lacks the ability to invade neighboring tissues.
Malignant tumour contrasts with the benign tumor in that the cells, here, are capable of invading into adjacent tissues. This type of tumor is thus cancerous as the cells grow out of control.
Lipoma is the benign tumor of fatty tissue.
Therefore, the correct answer is option B.
