benign tumour

Quick Reference

A nonmalignant tumour composed of proliferating (neoplastic) cells that does not invade locally or metastasize. From a cell-biological perspective, growth control has been lost but not positional control. Compression of adjacent tissue may produce a fibrous capsule of compressed tissue. Benign tumours can be life-threatening if the tumour is in a restricted space or causes obstruction.
