Can spinal cord compression be prevented?

In people with cancer, pressure may develop when a tumour in or near the vertebrae grows, weakens bone, or causes swelling around the spinal cord. Treatment before major nerve damage develops offers the greatest opportunity to preserve movement and bladder or bowel function.

The spinal cord carries signals between the brain and the body inside a narrow bony canal. Cancer involving the spine can narrow that space. Bone metastases and multiple myeloma can weaken vertebrae, while a nearby mass may press directly on nerves. Compression can occur despite appropriate cancer care, so prevention also means recognising the earliest warning signs.

A clinician may use a neurological examination and urgent spinal imaging when compression is suspected. The treatment plan can include medicine to reduce swelling, radiotherapy, surgery, or treatment directed at the cancer; the choice depends on the location, spinal stability, overall condition, and previous treatment.

Know the symptoms your oncology team wants reported immediately, especially if cancer has reached bone or you have a plasma-cell disorder. Mention new back or neck pain early, including pain that is severe, wakes you, worsens with coughing or straining, or travels around the chest or down a limb. Follow advice about imaging, cancer treatment, movement, braces, and pain medicines.

Avoid forceful spinal manipulation when vertebral weakness is suspected. If lifting or exercise causes new pain, stop and seek guidance about safe activity rather than testing the painful area repeatedly.

For anyone with cancer, new limb weakness, difficulty walking, numbness, altered sensation around the buttocks or genitals, or loss of bladder or bowel control requires emergency assessment. Severe or rapidly worsening back pain with any of these signs is also an emergency.

Contact the cancer team urgently for new, persistent back or neck pain even if strength and sensation seem normal. State that you have cancer and are concerned about spinal cord compression so the service can direct you appropriately. Do not drive yourself if weakness or loss of sensation makes travel unsafe.

Ask whether your cancer affects the spine, whether any vertebra is unstable, and which activities are safe. Clarify the emergency contact route outside clinic hours, what pain pattern should trigger a same-day call, and whether you need a personalised plan for imaging or bone-directed treatment.
