Multiple Choice

What is the primary difference between a benign tumor and a malignant tumor?

Benign tumors are always larger than malignant tumors.

Benign tumors can spread to other parts of the body, while malignant tumors cannot.

Malignant tumors are always less dangerous than benign tumors.

Malignant tumors can invade nearby tissues and spread to other parts of the body, while benign tumors do not.

Verified step by step guidance

Understand the basic definitions: A tumor is an abnormal growth of cells. Tumors can be classified as benign or malignant based on their behavior and potential to spread.

Identify the characteristics of benign tumors: Benign tumors are non-cancerous growths. They typically grow slowly and remain localized, meaning they do not invade nearby tissues or spread to other parts of the body.

Identify the characteristics of malignant tumors: Malignant tumors are cancerous. They have the ability to invade nearby tissues and spread to other parts of the body through a process called metastasis.

Compare the two types: The primary difference lies in their potential to spread. Malignant tumors can invade and metastasize, while benign tumors do not have this capability.

Clarify misconceptions: Size is not a definitive factor in distinguishing between benign and malignant tumors, and malignant tumors are generally more dangerous due to their invasive nature.
