What signs suggest a spinal tumor in a patient with back pain?

• A. Night pain, progressive non-mechanical pain, weight loss, and new focal neurological deficits.
• B. Pain worse with movement and improved with rest.
• C. Persistent morning stiffness for less than 30 minutes.
• D. Localized tenderness without neuro deficits.

Answer: (A)

Red flags in back pain point toward serious underlying problems such as a spinal tumor. The combination of night pain that is persistent and not explained by posture, ongoing progression of pain that is non-mechanical, unexplained weight loss, and new focal neurological deficits strongly suggests a space-occupying lesion or metastasis affecting the spine or spinal cord. Night pain is particularly concerning because it tends to persist despite rest and often indicates an inflammatory or neoplastic process rather than simple musculoskeletal pain. The progressive, non-mechanical nature means the pain isn’t tied to movement or activity, which helps distinguish it from common mechanical back pain. Weight loss signals a systemic illness, which raises suspicion for cancer. New focal neurological deficits—such as weakness, numbness, or changes in reflexes—reflect potential compression of neural structures by a tumor.

In contrast, pain that worsens with movement and improves with rest describes typical mechanical back pain, not a neoplastic process. Persistent morning stiffness lasting less than 30 minutes is more consistent with non-inflammatory or mechanical issues rather than a tumor, and localized tenderness without neurological deficits can occur with simple musculoskeletal problems rather than spinal neoplasia.
