For people who have severe back pain, it is natural to wonder whether or not the pain might be a sign of spinal cancer. While most back pain is unrelated to cancer or tumors, it is possible and important to check out. This article explains when back pain may be related to a spinal tumor, how to get an accurate diagnosis, and what to consider for treatment options.
Types of Spinal Tumors
A spinal tumor is an abnormal growth of cells within the spinal column. These tumors may be cancerous (malignant) or noncancerous (benign). A cancerous tumor is composed of abnormal cells that continue to divide uncontrollably and have the potential to spread via the blood or lymphatic system.
There are 2 general types of spinal tumors:
- Primary tumors originate in the spinal column. While most primary tumors are noncancerous, some are cancerous.
- Secondary tumors, also called metastatic tumors, have spread to the spine from another part of the body. Metastatic tumors are cancerous. About 90% of diagnosed spinal tumors are metastatic.1,2
Spinal tumors can also be classified by whether they are outside the spinal cord (extradural), within the spinal cord’s protective covering (intradural-extramedullary), or within the spinal cord itself (intramedullary).
How Spinal Cancer Pain May Feel
When back pain is caused by a cancerous spinal tumor, it typically:
- Starts gradually and worsens over time
- Does not improve with rest and may intensify at night
- Flares up as a sharp or shock-like pain in the upper or lower back, which may also go into the legs, chest, or elsewhere in the body
Other signs and symptoms that could potentially indicate the origin of back pain from cancer include unplanned weight loss, nausea, fever, chills, or other troubling symptoms.
How Spinal Cancer May Cause Back Pain
Tumors in the spinal column may cause back pain by:
- Expanding and/or weakening the bone
- Causing the vertebrae to easily fracture
- Compressing the spinal cord and/or spinal nerve roots
Additional factors, such as spinal instability, may also be involved in spinal tumors causing back pain.
The Course of a Cancerous Spinal Tumor
A cancerous spinal tumor’s rate of growth can vary depending on the type. A tumor may be relatively small and contained within the spine, or it could have already spread through blood or lymph (fluid that travels throughout the body) from another area of the body. An untreated cancerous spinal tumor is likely to keep growing and may become life-threatening.
Treatment options for spinal cancer may include radiation therapy, chemotherapy, immunotherapy, and/or surgical removal of the tumor. In cases when the patient is unlikely to tolerate surgery well or has advanced cancer, palliative care may be offered to reduce pain and stay as comfortable as possible, rather than removing the tumor.

When to See a Doctor
When unexplained back pain persists for a couple weeks despite rest and/or self-care, it is typically recommended to visit a doctor for a medical evaluation. Severe back pain that interferes with daily activities, or any back pain that is accompanied by red flag symptoms such as nausea or weight loss, requires an immediate medical evaluation. For people who currently have or previously had cancer, any new back pain needs to be evaluated by a doctor immediately.
It is also important to note that back pain rarely turns out to be cancer. Getting an accurate diagnosis for back pain from a medical professional is an important first step toward finding an effective treatment plan.
