Verified step by step guidance

Understand the definition of a malignant tumor: Malignant tumors are cancerous growths that have the ability to invade and destroy nearby tissue and spread to other parts of the body (metastasize).

Identify the characteristics of malignant tumors: They typically exhibit rapid and uncontrolled growth, which is a key feature distinguishing them from benign tumors.

Consider the ability to metastasize: Malignant tumors can spread to other parts of the body, which is a critical aspect of their behavior.

Evaluate the ability to invade surrounding tissues: Malignant tumors lack well-defined borders and can invade surrounding tissues, unlike benign tumors which are usually encapsulated.

Review the options given: Compare each option against the characteristics of malignant tumors. The correct answer should align with the known features of malignant tumors, such as rapid growth and the ability to invade and metastasize.
