In simple terms, dysplasia is the disordered growth of the cells. Dysplasia in general comprises of the increased growth of immature cells with a simultaneous reduction in the growth of mature cells, their numbers and their site of growth. For example, when the squamous epithelium of the esophagus is damaged by gastroesophageal reflux, the damaged cells are replaced by the glandular epithelium, which is more adapted due to survive high acidity. Hyperplasia vs Metaplasia vs Anaplasia vs Dysplasia vs Neoplasia Hyperplasia is the increase in number of cell. It is not considered … The term dysplasia is typically used when the cellular abnormality is restricted to the originating tissue, as in the case of an early, in-situ neoplasm. It is detected on endoscopy and confirmed histologically by the presence in the lower oesophagus of a metaplastic mucosa, the so-called specialised epithelium, which resembles incomplete intestinal metaplasia in the stomach.

Benign vs precancer: Metaplasia (on the cervix) is simply cell changes that are not typical for that area. It directly indicates a state when the cellular defect is constrained within the tissue origin, for instance in case of an in-situ neoplasm. Unlike in Dysplasia, in case of Metaplasia if the stimulus responsible for the transformation is either done away with or removed, the tissues instantly get back to the normal course of growth and prototype of differentiation.
