If a tumor is benign, what characteristic defines it?

A benign tumor is characterized by its non-invasive nature, meaning that it does not invade surrounding tissues. This distinction is essential when differentiating between benign and malignant tumors. Benign tumors typically remain localized and do not spread to distant sites in the body, allowing for easier treatment options, often including surgical removal. Unlike malignant tumors, benign tumors generally grow at a slower rate and do not have the ability to metastasize, which contributes to their relatively favorable prognosis. Understanding this characteristic is crucial for recognizing how benign tumors differ from their malignant counterparts and the implications for patient care.
