Benign tumors are characterized by their tendency to remain localized and not spread to distant sites in the body, which is what is meant by the term "typically do not metastasize." Unlike malignant tumors, which can invade surrounding tissues and metastasize to other parts of the body, benign tumors usually grow slowly, are well-defined, and do not have the ability to penetrate tissues aggressively. This lack of metastasis is a hallmark of benign tumors, which is significant in distinguishing them from malignant tumors that can have more severe implications for health due to their invasive nature and potential to spread.

While some benign tumors can cause local symptoms or health issues depending on their size and location, they generally do not produce systemic symptoms, which are more commonly associated with cancerous tumors. Their controlled growth pattern and lack of invasion into surrounding tissues are key factors that define their benign status in the context of tumor classification.
