What does the suffix "-scopy" indicate in medical terminology?

The suffix "-scopy" in medical terminology signifies a visual examination of a particular part of the body, often using a specialized instrument called a scope. This term originates from the Greek word "skopein," which means "to look" or "to examine." Various medical procedures incorporate "-scopy," such as endoscopy (examining the interior of the digestive tract) or bronchoscopy (examining the airways). The nature of these procedures highlights the focus on visualization and assessment of internal structures or functions, which is critical for diagnosis and treatment planning in medicine.

In contrast, the other options refer to different concepts: "opening" is often denoted by suffixes like "-stomy," "treatment" may involve terms ending in "-therapy" or other related suffixes, and "incision, to cut into" is typically indicated by suffixes such as "-otomy." Each of these uses a unique suffix that defines a different aspect of medical processes, further underscoring the specific role of "-scopy" as related to visual examination.
