What is characterized by abnormal development of tissue?

The term that refers to abnormal development of tissue is dysplasia. Dysplasia is a medical condition where cells within a tissue undergo changes in size, shape, and organization, often leading to an abnormal growth pattern. This condition can be a precursor to more serious diseases, including cancer, as it signifies that the cells are not developing normally. Understanding dysplasia is crucial in various fields, especially in pathology and oncology, as it helps in diagnosing and monitoring potential malignancies.

Dysentery refers to an intestinal infection, emphysema is a chronic lung condition affecting breathing, and dyspnea means difficulty in breathing, none of which relate to tissue development in the same way as dysplasia does.
