Which is listed as a complication of cancer involving the oral cavity?

• A. Graft rejection
• B. Empyema
• C. Osteonecrosis
• D. Fistula

Answer: (C)

When cancer involves the oral region, damage to the jawbone from treatment can lead to bone death in the jaw, known as osteonecrosis. This is a well-established complication, especially after radiation therapy to the head and neck or with drugs like bisphosphonates that are used to manage bone metastases. The result is exposed, nonhealing, often painful bone in the mouth that can become infected and difficult to manage—precisely what makes osteonecrosis the most characteristic and testable complication in this context. Graft rejection is related to transplanted tissue, not a typical cancer-related issue in the oral cavity. Empyema involves pus in the chest cavity, not directly connected to oral cancer. A fistula can occur after extensive surgery or radiation but is less specifically tied to the oral cavity as a listed complication in standard cancer care contexts.
