What does "malignant" imply about a condition?

The term "malignant" specifically refers to a condition that is harmful, dangerous, and indicative of cancerous growths. This implies that the disease has the potential to worsen over time and may pose a significant threat to life, potentially leading to death if not addressed appropriately. Such conditions are characterized by uncontrolled cell growth that can invade surrounding tissues and spread to other parts of the body, complicating treatment and increasing the risk of severe health consequences. This understanding underscores the seriousness of a malignant diagnosis, distinguishing it from benign conditions, which are typically non-threatening and do not exhibit the same aggressive behavior.
