The doctor pointed out that there are many reasons for nasal congestion. In addition to colds, runny noses or allergic attacks, some nasal diseases can also cause nasal congestion. Only unilateral persistent nasal congestion may be a benign nasal disease or a precursor to nasal cancer. These situations can't be judged by yourself. The only way is to go to the nasal clinic and check with scientific instruments to make a clear diagnosis.
It is usually a unilateral and persistent nasal obstruction caused by benign nasal diseases. Including nasal septum curvature, polypoid or fungal sinusitis, some benign tumors were released, but besides unilateral and persistent nasal congestion, they were accompanied by nosebleeds and ear swelling. You should be more careful when there is a lump in your neck, which is usually a precursor to nasal cancer. You should see a doctor as soon as possible, and don't delay the treatment.
How to distinguish the symptoms of halogen sinus tumor caused by nasal trauma?
Malignant tumors of nasal cavity and paranasal sinuses are called nasal cancer or nasopharyngeal carcinoma. We should master the common manifestations of nasal cancer for early detection and treatment. 1, nosebleeds and nosebleeds are the most common symptoms. When the cancerous tissue is very small and confined to the nasal cavity or sinuses, this symptom is the only "alarm" signal, and there is often little bleeding, sometimes only nosebleeds, so it is often ignored by patients. So pay special attention, especially to middle-aged people aged 40 to 40. If you have this symptom, you might as well ask a doctor to check it. 2. Unilateral nasal congestion and runny nose cancer appeared earlier, and nasal sinus cancer appeared later. With the enlargement of tumor tissue, nasal congestion becomes heavier and heavier, showing persistent nasal congestion. This is different from the general rhinitis with two nasal congestion alternations. After dropping 1% ephedrine solution, nasal ventilation could not be improved as obviously as rhinitis. In addition, when the tumor tissue necrosis or mixed infection, there will be a special smell of nasal mucus. 3, cheek swelling, pain and numbness This is mainly a symptom of maxillary sinus cancer. Some of these patients can feel the swelling under the local skin. 4. Eye symptoms include unilateral stereopsis, diplopia, red eye, runny nose, eye swelling and pain, and decreased vision. These symptoms usually appear earlier in ethmoidal sinus cancer. When maxillary sinus cancer and frontal sinus cancer spread to the orbit, eye symptoms will also appear. Patients often go to ophthalmology first and then to otolaryngology. The most common oral symptoms are toothache, loose teeth and difficulty in opening mouth. These symptoms are mainly related to maxillary sinus cancer. Because the roof of the mouth is the bottom wall of the maxillary sinus, the lesions of the maxillary sinus often have the symptoms of the above teeth, especially the symptoms of the first, second molars and second bicuspids on the affected side. Some upright people have almost all their upper teeth pulled out because of toothache, but the toothache has not been alleviated, and then cancer will drill out of the painful place. The diagnosis is clear, but the lesion has spread. 6. Other symptoms include swollen nose, swollen neck lymph nodes, headache and deterioration of general health, which are mostly symptoms of advanced cancer. Having said that, it must be pointed out that the above are common symptoms of nasal cancer, but as a single symptom, nasal cancer is not the most common cause of these symptoms, but mostly other diseases. This is a very important concept, otherwise it is easy to get cancer. Some diseases with the same symptoms, such as nosebleeds and nasal septum diseases; Nasal congestion is a common rhinitis; Eye and oral symptoms Common eye and tooth diseases. While being alert to nasal congestion, you should also consult your doctor carefully for examination and identification.
Li, a famous actor, suffers from nasal cancer. While everyone is sorry, there is a saying that rhinitis can lead to nasal cancer (it is reported that Li Changchun suffers from rhinitis). This makes many patients with rhinitis very worried, for fear that this rhinitis will one day become nasal cancer. Is there any scientific basis for this statement? The reporter interviewed Hua Qingquan, deputy chief physician of the Department of Otolaryngology, People's Hospital of Wuhan University.
Director Hua thinks this kind of worry is unnecessary, because so far, there is no research on rhinitis leading to nasal cancer in the medical field. Director Hua said that nasal cancer is a malignant tumor, which is a high incidence area in the Pearl River Delta of China, and the incidence rate in Wuhan is in the middle. As for the cause of nasal cancer, it is not clear at present, except that the disease is familial and related to EB virus infection. Director Hua pointed out that this does not mean that rhinitis has nothing to do with nasal cancer, because EB virus can cause upper respiratory tract infection, and sometimes this infection will have rhinitis symptoms.
What worries Director Hua is that the symptoms of nasal cancer are similar to rhinitis, with headache and stuffy nose, which makes some patients, especially those with a history of rhinitis, often wait until the late stage for treatment. Director Hua reminded patients that if the typical symptoms of nasal cancer often appear, the nose is bloody (that is, the sputum spit out by the nose is bloody), they should see a doctor. In addition, tinnitus and upper neck mass (late symptoms) may also be signs of nasal cancer.
It is understood that the 5-year survival rate of patients with advanced nasal cancer after radiotherapy is 30%-40%.
Epidemiological characteristics of 1 nasopharyngeal carcinoma
Nasopharyngeal carcinoma is a kind of head and neck tumor with high malignancy. Due to different regions, races and ages, the incidence rate varies greatly. Nasopharyngeal carcinoma is mainly found in Southeast Asia, especially in southern China (such as Guangdong, Guangxi, Fujian, Hunan and Jiangxi). ), and the yellow race.
