What does the suffix '-ectasis' refer to?

The suffix '-ectasis' is derived from Greek, where it signifies dilation or expansion. In medical terminology, it is commonly used to describe conditions associated with the abnormal enlargement of a vessel or cavity within the body. For example, bronchiolectasis refers to the dilation of the bronchi, and lymphangiectasis describes the dilation of lymphatic vessels.

Understanding the meaning of this suffix is crucial for interpreting medical terminology accurately, especially in oncology, where knowledge of the anatomical and physiological changes in tissues and organs can aid in diagnosis and treatment planning. Recognizing how dilation or expansion relates to various medical conditions can enhance an oncology data specialist's ability to collect, analyze, and communicate relevant clinical data effectively.
