What is a neoplasm?

A neoplasm is defined as an abnormal tissue growth resulting from uncontrolled cell division, which often forms a mass or lump known as a tumor. This growth can be benign, meaning it does not invade nearby tissues or spread to other parts of the body, or malignant, which signifies that it has the potential to invade tissues and metastasize (spread). The term "neoplasm" specifically refers to this process of abnormal cellular proliferation, distinguishing it from normal physiological growth.

The concept of a neoplasm is critical in fields such as oncology, as understanding the nature of these growths helps in diagnosing and treating various types of cancers and other proliferative disorders.
