Neoplasm is an abnormal mass of tissue as a result of neoplasia.
Neoplasia means new growth in Greek. It denotes abnormal proliferation of cells.
The growth of this clone of cells exceeds, and is uncoordinated with, that of the normal tissues around it.
One of the features of the neoplastic growth is that it persists in the same excessive manner even after cessation of the stimuli.
Neoplasms may be benign, pre-malignant or malignant.
The term tumor is synonymous with a neoplasm that has formed a lump.
Not all neoplasms form lumps.« Back to Glossary Index
