Suffix for tumor, mass is which of the following?

• A. -itis
• B. -oma
• C. -osis
• D. -algia

Answer: (B)

Suffix that names a tumor or neoplasm is -oma. This ending signals a growth or mass, as seen in lipoma (fat tumor), osteoma (bone tumor), and adenoma (glandular tumor). In contrast, -itis means inflammation, -osis indicates an abnormal condition or process, and -algia means pain. So -oma is the appropriate ending when referring to a tumor or mass.
