Which medical term indicates a process or condition?

The suffix "-oma" refers specifically to a tumor or a mass, which indicates a process or condition involving abnormal growth. In medical terminology, it is commonly used to denote types of tumors, whether benign or malignant, such as "carcinoma" (cancer) or "lipoma" (a benign tumor of fatty tissue). This suffix highlights a condition due to its association with pathological growth processes.

The other terms, while related to medical conditions, do not universally indicate a process or condition in the same way. "-pexy" refers to the surgical fixation of an organ or tissue; "-atosis" describes a condition characterized by an abnormal state, often involving an increase in something, such as in "steatosis" (fatty change); and "disease" is a general term denoting a pathological condition rather than a specific process. Thus, "-oma" is the most precise term indicating a process or condition.
