Question 3:

What is the main difference between benign and malignant tumors?

A) Benign tumors are cancerous, while malignant tumors are not

C) Benign tumors are encapsulated, while malignant tumors are not

Benign tumors are non-cancerous and do not invade nearby tissues or spread to other parts of the body. They are typically encapsulated, meaning they have a defined boundary. Malignant tumors, on the other hand, are cancerous and can invade nearby tissues and spread to other parts of the body.

B) The formation of a tumor
C) The spread of cancer cells to other parts of the body
D) The removal of a tumor through surgery

Show Answer

Explanation: The correct answer is C) The spread of cancer cells to other parts of the body.
