CMetastasis to the epidural spine from breast cancer is indeed often associated with worsening back pain in the supine position or with the Valsalva maneuver, due to increased venous pressure in the vertebral venous plexus which exacerbates the pain. Radicular pain in the thoracic spine, which can be caused by metastatic lesions, is typically unilateral because it usually results from compression or irritation of a single nerve root.
