What are the symptoms of nasopharyngeal carcinoma bone metastasis?

Nasopharyngeal carcinoma bone metastasis is asymptomatic in the early stage. When the tumor grows to a certain extent, it will compress or irritate the sensory nerve endings, or cause bone damage and pain. The pain starts intermittently and then becomes continuous, especially at night, and cannot be reduced by rest or braking.

The pain is significantly aggravated when pressing the bone metastasis. Some patients are accompanied by low fever or anemia. Severe bone and skin damage may be a pathological fracture. If it is a cervical fracture, it can compress the cervical spinal cord, causing weakness in the limbs, difficulty breathing, and even respiratory arrest. Caries can appear in the late stage.
