Spinal tumors are classified according to their location in the spine.
A nervous system (neurologic) examination may find the location of the tumor.
A small number of spinal tumors occur in the nerves of the spinal cord itself. Most often these are ependymomas and other gliomas.
Tumors that start in spinal tissue are called primary spinal tumors. Tumors that spread to the spine from some other place (metatastasis) are called secondary spinal tumors.
The cause of primary spinal tumors is unknown. Some primary spinal tumors occur with genetic defects. A spinal tumor is much less common than a primary brain tumor.
Back pain, especially in the middle or lower back, is the most frequent symptom of both noncancerous and cancerous spinal tumors. The pain may be worse at night or on awakening. It also may spread beyond your spine to your hips, legs, feet or arms and may become more severe over time in spite of treatment.
Spinal tumors progress at different rates. In general, cancerous tumors grow more quickly, whereas noncancerous tumors may develop very slowly, sometimes existing for years or even decades before causing problems.
Both noncancerous and cancerous spinal tumors can compress spinal nerves, leading to a loss of movement or sensation below the level of the tumor and sometimes to changes in bowel and bladder function. Nerve damage is often permanent, and disabilities are likely to continue even after the tumor is removed. Depending on its location, a tumor that impinges on the spinal cord itself may be life-threatening.
The three most commonly used treatments are surgery, radiation, and chemotherapy. Doctors also may prescribe steroids to reduce the swelling inside the CNS.
Symptoms of brain and spinal cord tumors generally develop slowly and worsen over time unless they are treated. The tumor may be classified as benign or malignant and given a numbered score that reflects how malignant it is. This score can help doctors determine how to treat the tumor and predict the likely outcome, or prognosis, for the patient.
