Bone metastasis of nasopharyngeal cancer can invade the skull, sternum, lumbar or thoracic vertebrae, bone disc, spine and other bones. Once the bone metastasis of nasopharyngeal carcinoma enters into advanced stage, it may manifest as persistent headache when it invades the skull, which is difficult to be relieved by medication, and sometimes may manifest as unilateral migraine. When nasopharyngeal cancer invades the sternum, it may cause chest pain and other symptoms. Clinically, once nasopharyngeal carcinoma patients have bone metastasis in related parts, they may have deformation and activity disorder, such as pelvic area.
