If the proliferating cells invade surrounding tissues, the resultant tumor is malignant; if they do not, it is benign. Some benign neoplasms may be fatal, including histologically benign brain tumors that grow and displace normal brain tissue in the confined space of the skull, and hepatocellular adenomas that rupture and cause bleeding into the peritoneal cavity. Some benign tumors such as intestinal polyps are considered premalignant lesions and confer a high risk of progression to malignancy. The term cancer usually implies a malignant tumor (malignancy), but refers also to brain tumors and some other benign neoplasms.
