Which characteristic is NOT associated with benign tumors?

Benign tumors are characterized by their non-cancerous nature, meaning they do not possess the ability to invade surrounding tissues or metastasize to distant sites in the body, which is typically seen in malignant tumors. The correct answer highlights that benign tumors lack a cancerous nature, distinguishing them from cancerous (malignant) tumors.

In addition to the absence of cancerous properties, benign tumors generally exhibit slow growth rates compared to their malignant counterparts. They are also non-invasive, meaning they do not infiltrate adjacent tissues, which further supports their classification as benign. Additionally, benign tumors tend to remain localized, often encapsulated, and do not spread to other parts of the body, which is a key feature that differentiates them from malignant tumors that can grow aggressively and metastasize.
