Spine metastasis refers to the spread of cancer cells from a primary tumor site in another part of the body to the spine. This condition is one of the most common sites for cancer to metastasize, particularly in the thoracic and lumbar regions. Symptoms can include back pain that is persistent and often worse at night, numbness, tingling, or weakness in the limbs, changes in bowel or bladder function, and, in severe cases, paralysis if the spinal cord is compressed. Diagnosis typically involves imaging studies such as MRI or CT scans, and may include a biopsy to confirm the presence of cancerous cells. Treatment options depend on the type of primary cancer, the location and extent of the metastasis, and the overall health of the patient. They can include radiation therapy, surgery, or medications such as steroids or pain relievers to manage symptoms and slow progression. Early diagnosis and a multidisciplinary approach to treatment can help improve quality of life and manage symptoms effectively.
