Benign tumors are characterized by their non-invasive nature, meaning they do not invade surrounding tissues or organs, which is a key distinguishing feature compared to malignant tumors. Additionally, they are often encapsulated, which means they are surrounded by a fibrous capsule that helps to separate them from the surrounding tissues, reducing the likelihood of spreading. Their growth pattern is typically slow, which is another characteristic that differentiates them from more aggressive malignant tumors.
The statement that benign tumors can spread throughout the body is inaccurate. Benign tumors remain localized and do not metastasize, or spread to distant sites, which is a hallmark of malignant tumors. Therefore, this characteristic is not true about benign tumors, reinforcing that they are generally not life-threatening and can often be managed effectively.
