( Neoplasm)
Neoplasia (new growth in Greek) is the abnormal proliferation of cells, resulting in a structure known as a neoplasm. The growth of this clone of cells exceeds, and is uncoordinated with, that of the normal tissues around it. It usually causes a lump or tumor. Neoplasms may be benign, pre-malignant or malignant. In modern medicine, the term tumor is synonymous with a neoplasm that has formed a lump. In the past, the term tumor was used differently. Some neoplasms do not cause a lump. A neoplasm can be benign, potentially malignant (pre-cancer), or malignant (cancer). [1] Because neoplasia includes very different diseases, it is difficult to find a definition that describes them all. [2] The definition of the British oncologist R.A. Willis is widely cited A neoplasm is an abnormal mass of tissue, the growth of which exceeds and is uncoordinated with that of the normal tissues, and persists in the same excessive manner after cessation of the stimulus which evoked the change.[3]
