The suffix "-ectomy" refers to which of the following?

The suffix "-ectomy" is derived from the Greek word "ektome," which means "excision" or "cutting out." In medical terminology, it specifically denotes a surgical procedure in which a body part or organ is removed. For instance, a "appendectomy" refers to the surgical removal of the appendix. This term is commonly used in various surgical contexts, indicating that something is being excised.

In contrast, the other choices refer to different medical processes or characteristics. Inflammation is indicated by the suffix "-itis," a diagnostic procedure might include terms such as "-oscopy," and a condition of blockage is typically indicated by terms like "-stenosis." Each of these terms uses different suffixes that convey specific meanings related to their respective medical scenarios. Thus, the correct association of "-ectomy" with surgical removal is clearly established and reflected in numerous medical terminologies.
