In patients with back or neck pain, which finding is a cancer-related red flag signaling possible metastatic disease?

• A. New unexplained weight loss
• B. Night pain
• C. History of cancer
• D. Generalized fatigue

Answer: (A)

In this scenario, the key idea is that new, unexplained weight loss signals a systemic process that could be due to cancer spreading to the spine or surrounding structures. Weight loss reflects metabolic changes from tumor activity and is less likely to be caused by ordinary musculoskeletal pain, making it a strong red flag for metastatic disease. When back or neck pain accompanies unexplained weight loss, it warrants urgent medical evaluation and imaging to rule out cancer and coordinate care. While night pain and a history of cancer are important considerations, the appearance of new weight loss in a patient with spine or neck symptoms is the most direct indicator that metastatic involvement could be present, thus making it the best answer.
