What does the suffix "-itis" refer to in medical terms?

The suffix "-itis" is commonly used in medical terminology to indicate inflammation of a specific organ or tissue. For example, "arthritis" refers to the inflammation of the joints, and "dermatitis" signifies inflammation of the skin. This suffix helps healthcare professionals quickly identify the nature of the condition being described, specifically that it involves inflammatory processes. Understanding this suffix is crucial for medical coding, diagnosis, and communication within a clinical setting, as it conveys essential information about the condition's pathology.

In contrast, the other options reference different medical concepts: “growth or tumor” refers to neoplasms; “condition or disease” is more generalized and does not specifically indicate inflammation; and “excision or removal” pertains to surgical procedures rather than an inflammatory response. Thus, the correct association of "-itis" with inflammation is key in medical terminology.
