Find out about spinal cord compression, the symptoms and how it is diagnosed.
Spinal cord compression happens when pressure on the spinal cord stops the nerves working normally.
The spinal cord
The spinal cord is a long bundle of nerves that stretches from the brain to the lower part of the back. The nerves extend into three regions. They send messages to control movement and feeling in different parts of our body. The bones of the spine are called vertebrae and they protect the spinal cord.
What spinal cord compression is
Spinal cord compression happens when there is pressure on the spinal cord. Cancer in the spinal bones can cause pressure but there are also other causes.
This condition has different names depending on where the cancer started. You may hear it called:
- malignant spinal cord compression when the cancer started in the spine
- metastatic spinal cord compression when the cancer cells have spread into the spinal bones from another part of the body
Pressure on the spine stops the nerves working normally.
Who is at risk
Around 3 to 5 in 100 people (3 to 5%) with cancer develop spinal cord compression. Almost any type of cancer can spread to the spine.
You’re at higher risk of developing spinal cord compression if you have cancer that:
- has already spread to your bones
- is at high risk of spreading to your bones, such as prostate, breast or lung
- started in your spine
Symptoms of spinal cord compression
Symptoms depend on where the pressure is in the spinal cord.
Pain is often the first symptom and more than 9 out of 10 people (90%) with spinal cord compression have it. The pain could be:
- anywhere in your back or neck or it may feel like a band around your body
- worse when you cough, sneeze or go to the toilet
- getting worse or doesn’t go away
- stopping you sleep or wakes you up at night
Other symptoms are:
- changes to sensations in your body, such as pins and needles or numbness
- weakness in your legs or arms
- not being able to open your bladder or bowels
- difficulty controlling your bladder or bowels
- erection problems
What to do if you have symptoms
Contact your hospital team straight away if you have any symptoms of spinal cord compression. You should have an emergency number to call. Don’t worry about calling anytime, even at night or at the weekend.
Your area should have a senior doctor who can make a decision about what should happen next. They might ask you to go to hospital straight away for a scan. You might need to go to a hospital that is not your usual hospital.
Tests for spinal cord compression
You’ll have an MRI scan if your doctors think you might have spinal cord compression.
The National Institute for Health and Care Excellence (NICE) has produced guidance on diagnosing and treating spinal cord compression. NICE recommends that you should have the scan within a week of telling your team about your symptoms. You should have this scan within 24 hours if you have any weakness or changes in sensation.
You might also have a CT scan.
Starting treatment early helps stop the symptoms getting worse or becoming permanent.
It can be difficult to cope with the changes caused by spinal cord compression. It’s normal to feel a range of emotions, including being upset and frightened. There is no ‘right’ way to feel and everyone is different.
Tell your healthcare team how you feel. They can find the best person to help.
You can do some supportive things. Getting information about spinal cord compression and your cancer can help you cope, so you know what to expect. Take some time out to look after yourself. Some hospitals have a complementary therapy service you could access for free..
