Which term indicates a swelling or tumor in medical terminology?

The term that indicates a swelling or tumor in medical terminology is "cele." This suffix is derived from the Greek word "kele," meaning a protrusion or swelling. It is commonly used in the formation of medical terms to refer to various types of hernias, cysts, or abnormal swellings in different parts of the body, such as in the terms "hydrocele" (a fluid-filled sac around a testicle) or "meningocele" (a type of spina bifida where the protective membranes of the spinal cord protrude through a defect in the spine).

Understanding this term is crucial in medical practice, as it helps in identifying and naming conditions related to swelling or tumors across various anatomical sites.

The other terms presented refer to different medical concepts: "atresia" pertains to the absence or closure of a normal body opening or passage, "dynia" indicates pain, usually in association with a specific part of the body, and "myasthenia" refers to muscle weakness or fatigue. These terms do not convey the idea of a swelling or tumor, thus reinforcing why "cele" is the correct choice.
