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

Benign tumors are always larger than malignant tumors.

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

Malignant tumors are always non-cancerous, while benign tumors are cancerous.

Benign tumors can invade nearby tissues, while malignant tumors cannot.

Verified step by step guidance

Understand the definition of a tumor: A tumor is an abnormal growth of cells that can be benign or malignant.

Define a benign tumor: Benign tumors are non-cancerous growths that do not spread to other parts of the body. They are usually localized and can often be removed surgically.

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

Compare the ability to spread: The primary difference is that malignant tumors can metastasize, meaning they can spread to distant organs and tissues, whereas benign tumors remain localized.

Clarify misconceptions: Benign tumors are not cancerous and do not invade nearby tissues, while malignant tumors are cancerous and can invade and spread.
