Most nasal cancers refer to nasopharyngeal cancer, and a few are nasal cancers. If there is bleeding, it may be bright red, that is, fresh blood. Of course, there is also old bleeding, which is dark red. Based on the symptom of bleeding alone, there is no way to diagnose nasal cancer or the type of nasopharyngeal cancer. Generally, pathological examinations such as nasopharyngoscopy are required to confirm whether it is nasal cancer or nasopharyngeal cancer. Nasopharyngeal cancer has certain geographical and family clustering phenomenon, and Guangdong Province is the province with high incidence. Nasopharyngeal cancer also has some other symptoms, such as neck lumps, nasal congestion, dizziness and so on. After the diagnosis is confirmed by biopsy pathology, radiotherapy is mainly used. Radiotherapy can be combined with simultaneous chemotherapy, as well as adjuvant chemotherapy after radiotherapy. If nasal cancer can be treated surgically, we can also consider surgery for radical treatment and nasal reconstruction after surgery, which can also be combined with radiotherapy and other anti-tumor treatments.
