What is the difference between benign and malignant neoplasms? Does one turn into the other?

In brief: Agree w/Dr Contreras

Benign neoplasm means that a growth is not cancerous.
Sometimes, a premalignant tumor has the potential of turning into cancer ex: adenomatous polyps in the colon, actinic keratosis in the skin. Extremely rarely a completely benign tumor (ex:lipoma, leiomyoma) can turn into cancer/malignancy (ex:liposarcoma, leiomyosarcoma). Majority of the time a benign tumor stays benign (noncancerous).

In brief: Good and bad

Benign tumors (also called neoplasms) have an extremely low risk of becoming aggressive, and spreading to other parts of the body.
Malignant neoplasms (also known as cancer) show the characteristics that put it at risk for spreading to other parts of the body and causing other problems. If benign tumors accumulate damage over time, they can degenerate into malignant tumors.
