Verified step by step guidance

Begin by understanding the definitions of benign and malignant tumors. Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body. Malignant tumors are cancerous and have the ability to invade and destroy nearby tissue and spread to other parts of the body.

Consider the characteristics of benign tumors. They typically grow slowly and are encapsulated, meaning they are contained within a protective layer of tissue, which prevents them from spreading.

Examine the characteristics of malignant tumors. These tumors often grow rapidly, invade surrounding tissues, and can metastasize, which means they can spread to distant sites in the body through the bloodstream or lymphatic system.

Evaluate the statements given in the problem. The statement 'Benign tumors have not spread to other sites' is correct because benign tumors remain localized and do not metastasize.

Analyze the statement 'Malignant tumors have not lost growth or control.' This is incorrect because malignant tumors have lost growth control, allowing them to grow uncontrollably and spread to other parts of the body.
