The Main Difference(s) Between a Malignant and a Benign Tumor

Question

The main difference(s) between a malignant and a benign tumor is/are that the benign tumor:
A) Is encapsulated and grows slowly.
B) Is sometimes anaplastic.
C) Has the ability to spread through blood and lymph.
D) Both A and B

Accepted Answer

A benign tumor is encapsulated and grows slowly, while a malignant tumor is not encapsulated and grows rapidly. Option B is incorrect because being anaplastic is a feature of malignancy, not benignancy. Option C is also incorrect because a benign tumor does not have the ability to spread through blood and lymph. Option D is partially correct, but only option A is the best choice.
