Which of the following terms is related to surgical removal?

The suffix "-ectomy" is commonly used in medical terminology to indicate the surgical removal of a specific body part or tissue. It derives from the Greek word "ektome," meaning "to cut out." For example, a "appendectomy" refers to the surgical removal of the appendix, while a "hysterectomy" denotes the removal of the uterus. This term directly relates to surgical procedures, highlighting its relevance in the context of the question.

Other options present different medical terms but do not specifically pertain to surgical removal. For instance, "dyspnea" refers to difficulty breathing, "dysuria" relates to painful urination, and "ecchymosis" describes a discoloration of the skin resulting from bleeding underneath, commonly known as a bruise. Thus, "-ectomy" is the term that clearly aligns with the concept of surgical removal.
