What characteristic is not associated with benign tumors?

Benign tumors are typically characterized by several key features that distinguish them from malignant tumors. They are non-invasive, meaning they do not invade surrounding tissues or organs, which is a primary reason they are considered less dangerous. Additionally, benign tumors do not metastasize, which means they do not spread to other parts of the body, further indicating their less aggressive nature.

They also generally do not pose a significant threat to health. This is because they are often well-circumscribed and can be removed surgically if necessary, and they tend to grow slowly.

While it is possible for some benign tumors to cause discomfort or pain due to their size or location, this is not a universal characteristic. Pain associated with benign tumors can depend on various factors, such as their pressure on nearby structures or nerves, but it is not an inherent trait of benign tumors themselves. Therefore, while some individuals may experience pain, it is not a defining characteristic of benign tumors as a whole.
