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.

Define benign tumors: 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 (metastasize).

Define malignant tumors: Malignant tumors are cancerous growths. They have the ability to invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system, a process known as metastasis.

Clarify the concept of metastasis: Metastasis is the process by which cancer cells spread from the original tumor site to other parts of the body, forming new tumors. This is a key characteristic of malignant tumors.

Identify the key difference: The main difference between benign and malignant tumors is that benign tumors do not metastasize, whereas malignant tumors do. This distinction is crucial in understanding the potential impact and treatment strategies for each type of tumor.
