Why does the nose bleed? nasal pharyngeal cancer

Nasopharyngeal cancer also has symptoms of nosebleeds, but nosebleeds of nasopharyngeal cancer have their own characteristics: First, nasopharyngeal cancer, as its name implies, is a cancer of the nasopharynx. Nasopharyngeal cavity is located at the back end of nasal cavity. Nasopharyngeal nosebleeds are mostly dark red and old nosebleeds that are sucked back from nasal cavity after getting up in the morning. Second, nosebleeds of nasopharyngeal carcinoma generally do not blow out from the front nostril; For you, your nosebleed is blown from the front nostril, indicating that the part of nasal bleeding is near the front end, obviously not in the nasopharynx. In addition, there are many reasons for bleeding like you, such as bleeding in the anterior lower part of nasal septum. It is called Creutzfeldt-Jakob disease area in medicine. The mucosa here is very thin, and the capillaries are rich and superficial. The cavity here is prone to rupture due to dryness, nose picking or even forced defecation, causing capillary rupture and bleeding. One of the characteristics of this kind of bleeding is that it is difficult to find the bleeding focus without bleeding. Another common cause is hemangioma of nasal cavity or sinus. There is a kind of nasal polyp called hemorrhagic nasal polyp, which is very easy to bleed. This is because this kind of nasal polyp contains more vascular components. You have a history of nasal polyps yourself, so you should first consider the diagnosis from the past medical history. Of course, there are many reasons for nosebleeds, such as systemic diseases: hypertension (mostly adults and above, with large and severe bleeding), blood system diseases (abnormal bleeding time' bleeding point or ecchymosis on the whole body skin) and so on. The diagnosis of diseases starts with common diseases and frequently-occurring diseases. After all, cancer is a minority, and the onset age of cancer is mostly over 60 years old.
