Which term means abnormal development or growth of cells, tissues, or organs?

• A. Dysphonia
• B. Bacteria
• C. Dysplasia
• D. Infectious Disease

Answer: (C)

Dysplasia describes abnormal development or growth of cells, tissues, or organs. It means that the cells within a tissue are growing in a disordered way, with changes in size, shape, and organization of the tissue architecture. This is often used to label premalignant changes, such as cervical dysplasia, where abnormal cells are present but have not invaded deeper tissues yet. Dysplasia can vary in severity and may regress, remain stable, or progress to neoplasia if the underlying factors persist. In contrast, a term like dysphonia refers to a problem with the voice, bacteria are microscopic organisms, and infectious disease describes illness caused by pathogens. Those concepts describe different phenomena, not the structural abnormality of tissue growth implied by dysplasia.
