What is metastatic spine disease?
The spine is one of the most common sites for cancer to spread. Deposits in the vertebrae can weaken the bone, causing pain and sometimes collapse, and can press on the spinal cord or nerves. This is treated as part of your overall cancer care rather than as an isolated spine problem.
Symptoms
- Persistent back or neck pain, often worse at night and unrelated to activity
- New pain in someone with a known cancer diagnosis, always worth reporting
- Weakness, numbness, or heaviness in the arms or legs
- Difficulty walking, or a change in balance
- Sudden severe pain suggesting a vertebra has fractured
Urgent
Seek urgent medical care for new or worsening weakness, numbness in the saddle area, or any change in bowel or bladder control. Spinal cord compression from metastatic disease is an emergency, and outcomes depend heavily on how quickly it is treated.
How it is diagnosed
MRI of the whole spine is usually preferred, because deposits are often present at more than one level. CT assesses bone quality and stability. The wider oncological workup (identifying the primary cancer if unknown, and staging it) runs alongside and shapes what spinal treatment is appropriate.
How treatment is planned
Decisions are made jointly with medical and radiation oncology. The considerations are the stability of the spine, whether neural structures are compressed, how radiation-sensitive the tumor is, and your overall health and goals. Many patients are managed with radiation and systemic therapy, with bone-protective medication where indicated.
When surgery is considered
Surgery is considered for mechanical instability, for cord compression, particularly where radiation alone is unlikely to relieve it quickly enough, or for pain from a structurally failing vertebra. The aim is to stabilize and decompress with an operation proportionate to your situation, supporting the oncological plan rather than competing with it.
