What are the late-stage symptoms of nasopharyngeal cancer?

The late-stage symptoms of nasopharyngeal carcinoma are varied and severe, mainly including the following aspects: 1. **Enlarged neck lymph nodes**: In advanced nasopharyngeal carcinoma, enlarged neck lymph nodes are commonly observed, with an incidence rate as high as 79.37%. The enlargement can occur unilaterally or bilaterally, and the nodes are typically hard and possibly adhered to surrounding tissues. 2. **Ear symptoms**: Due to tumor compression or obstruction of the Eustachian tube, symptoms such as tinnitus and hearing loss may occur. 3. **Cranial nerve damage**: As the tumor infiltrates surrounding tissues, it may compress cranial nerves, leading to symptoms of cranial nerve damage such as headache, facial numbness, double vision, and vision loss. 4. **Eye symptoms**: If the tumor invades the orbit or the nerves related to the eye, symptoms such as visual impairment, proptosis (bulging eyes), and restricted eye movement may occur. These symptoms not only affect the patient's quality of life but also increase the difficulty of treatment. Therefore, patients should seek timely medical attention for professional diagnosis and treatment once related symptoms appear.
