Nasal congestion caused by nasopharyngeal cancer is somewhat different from common nasal congestion, mainly in the area of nasal congestion as well as treatment. Nasal congestion caused by nasopharyngeal cancer is usually unilateral in the early stage, and with the growth and development of tumor, bilateral nasal congestion will appear gradually. Ordinary nasal congestion usually appears alternately and intermittently, and the side of nasal congestion will be changed after the patient changes the side lying position. Nasal congestion caused by nasopharyngeal cancer is usually ineffective when treated with glucocorticoid; for example, nasal congestion will not be relieved when using budesonide nasal spray and beclomethasone propionate nasal spray; however, common nasal congestion usually has obvious improvement after being treated with these drugs. Nasopharyngeal cancer also causes patients to suffer from tinnitus, blood in the nasal mucus, numbness and headache in the face, and if the situation is more serious, it also affects vision. When patients have symptoms of nasal congestion, they should seek medical checkup in time and treat for the cause of the disease to avoid delaying the condition.
