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 characteristics.

Benign tumors are non-cancerous growths. They tend to grow slowly and do not invade nearby tissues or spread to other parts of the body. They are usually encapsulated and have well-defined borders.

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. They often have irregular borders and can grow rapidly.

Evaluate the statements given in the problem: The statement 'Malignant tumors can invade nearby tissues, while benign tumors do not' is correct based on the definitions of benign and malignant tumors.

Consider the other statements: 'Benign tumors are always larger than malignant tumors' is incorrect as size is not a defining characteristic. 'Benign tumors are composed of cancerous cells' is incorrect as benign tumors are non-cancerous. 'Malignant tumors are less likely to spread to other parts of the body' is incorrect as malignant tumors are characterized by their ability to spread.
