3,4 -- Benign neoplasms are localized growths. They form a solid mass, have well-defined borders, and frequently are encapsulated. Benign neoplasms tend to respond to the body’s homeostatic controls. Thus, they often stop growing when they reach the boundaries of another tissue (a process called contact inhibition). They grow slowly and often remain stable in size. Because they are usually encapsulated, benign neoplasms often are easily removed and tend not to recur. In contrast to benign neoplasms, malignant neoplasms grow aggressively and do not respond to the body’s homeostatic controls. Malignant neoplasms are not cohesive, and present with an irregular shape. Instead of slowly crowding other tissues aside, malignant neoplasms cut through surrounding tissues, causing bleeding, inflammation, and necrosis (tissue death) as they grow.
