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 benign tumors: Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body.

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

Compare the invasiveness: The primary difference is that benign tumors do not invade nearby tissues, whereas malignant tumors do.

Clarify misconceptions: Benign tumors are not cancerous and do not spread through the bloodstream, while malignant tumors can spread through the bloodstream or lymphatic system.
