What is the meaning of the suffix "-otomy"?

The suffix "-otomy" is derived from the Greek word "tomia," which means "to cut." In medical terminology, it refers specifically to a surgical procedure that involves cutting into a body part to gain access for treatment, examination, or removal purposes. This is why "cutting" is the correct interpretation of the suffix.

For instance, in the term "appendectomy," it indicates the surgical cutting to remove the appendix, emphasizing the action of cutting. Other options do not capture this specific action associated with the suffix; "opening" typically relates to procedures that may create an entrance but does not convey the action of cutting itself, while "condition" and "tumor" refer to states or growths rather than the act of cutting. Therefore, recognizing the precise definition of "-otomy" as relating to cutting provides clarity in understanding its use in medical contexts.
