Which term contains the MESO- prefix referring to the middle area and is a condition?

• A. Mesothelioma
• B. Meson
• C. Mesolalia
• D. Mesogram

Answer: (A)

MESO- denotes the middle area, and when a term ends with -oma, it signals a tumor or growth. Mesothelioma is a malignant tumor arising from the mesothelium, the lining of body cavities such as the pleura and peritoneum. Because it combines the middle-area prefix with a disease-causing tumor meaning, it is a medical condition. The other terms don’t describe a middle-area disease: a meson is a subatomic particle, mesolalia isn’t a standard disease term, and a mesogram is a diagram, not a condition.
