A neoplasm is benign when it grows in an unregulated fashion without tissue invasion. The presence of both features is characteristic of malignant neoplasms. Cancers are named based on their origin: those derived from epithelial tissue are called carcinomas, those derived from mesenchymal tissues are sarcomas, and those derived from hematopoietic tissue are leukemias or lymphomas.
