cancer Neoplasms are diseases characterized by abnormal proliferation of cells. If the proliferating cells do not invade surrounding tissues the result of tumor is benign; if they do, it is malignant 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
