Which medical term is used for the enlargement of an organ?

The term that is used to describe the enlargement of an organ is "megaly." This term is derived from the Greek word "megale," which means "great" or "large." In medical terminology, "megaly" is often prefixed with the name of the organ that is enlarged, such as "hepatomegaly" for liver enlargement or "cardiomegaly" for heart enlargement.

While "hypertrophy" indicates the increase in the size of an organ or tissue through the enlargement of its cells, it is more specific and does not universally apply to all types of organ enlargement. "Atrophy" refers to the reduction in size or wasting away of an organ, while "hypoplasia" is the underdevelopment or incomplete development of an organ or tissue. Therefore, "megaly" is the most accurate term for general organ enlargement.
