Nasoscopy was normal last year, this year it is possible to be cancerous, regular checkups are recommended. Nasopharyngoscopy can clarify whether there is inflammation, nasal polyps, nasal mass, etc. in the nasal cavity. If the nasopharyngoscopy was normal last year, but the doctor ordered to continue the nasopharyngoscopy this year, it means that there is a certain hidden danger in the nasal cavity, and it is necessary to check to clarify the situation of the nasal cavity. If it was normal last year, the possibility of cancer this year will not be very high, but it cannot be ruled out, so it is important to have regular checkups. Nasopharyngeal cancer patients mainly have symptoms such as nasal congestion, snot blood, nosebleed, headache, etc. If patients have these symptoms, they should go to the hospital in time for examination and clarification. Early stage nasopharyngeal cancer patients can effectively control the disease and prolong the survival time through radiotherapy. Daily patients should pay attention to diet, reduce the intake of pickled food and smoke less.
