What suffix is used to denote the process of cutting or incision?

The suffix that denotes the process of cutting or incision is -tomy. This suffix is derived from the Greek word "tomia," which means cutting. It is frequently used in medical terminology to describe surgical procedures involving incisions into organs or tissues. For example, "laparotomy" refers to the surgical incision into the abdominal cavity, and "tracheotomy" denotes an incision made in the trachea.

The other options represent different medical concepts: -scopy refers to the process of viewing or examining an internal body structure, often using a scope (like in "endoscopy"), -logy denotes the study of a particular subject (for example, "biology" is the study of life), and -itis indicates inflammation of a particular organ or tissue (as seen in "appendicitis," which refers to the inflammation of the appendix). Each of these suffixes conveys a very different meaning from -tomy, which is specifically focused on cutting or incision.
