Final answer:
The suffix '-itis' indicates infection or inflammation of a particular part of the body and is not related to cancerous growths or genetic disorders.
Step-by-step explanation:
When the name of a condition ends with the suffix "-itis," this indicates infection or inflammation of a specific organ or type. This suffix is used to name various inflammatory diseases, where "itis" denotes the inflammation process itself. For example, peritonitis is the inflammation of the peritoneum, and meningitis refers to the inflammation of the meninges, the protective membranes covering the brain and spinal cord. It is important to note that -itis is not associated with cancerous growth nor genetic disorders, as cancer is characterized by uncontrolled cell growth and is referred to as malignant neoplasm, while genetic disorders are caused by mutations in genes or chromosomal alterations.
