Propaganda slogans stay away from nasopharyngeal carcinoma

Nasopharyngeal cancer will have this kind of performance, but this kind of situation is most common in dry weather, and local infection is the most common. Therefore, it may be better to go to the otolaryngology department first and stay moist. Nosebleed, stuffy nose, tinnitus, etc. It may be an early symptom of nasopharyngeal carcinoma, so you should go to the hospital for further examination in time to remind your friends that if you find this phenomenon, don't be careless and think it is a trivial matter, which may hide your worries. In the past two months, when Uncle Wang got up in the morning, his nose was often congested, and sometimes he sucked back nosebleeds from his mouth. At first, he thought it was the dry weather that caused the nosebleed, and he didn't care too much. However, two months later, the situation has not improved. So, Wang came to the hospital for otolaryngology, and the doctor gave him a nasopharyngoscopy and pathological examination, and finally he was diagnosed with nasopharyngeal carcinoma. For many people, nose bleeding is a trivial matter, but if bloody secretions appear repeatedly in the nose, the nose is pale pink, or there is blood in the sputum, this is a "big deal". Because this situation, which is called "reinfusion with blood" in medicine, is likely to be an early signal of nasopharyngeal carcinoma. Nasopharyngeal carcinoma is the most common malignant tumor in the head and neck, and it is easy to be misdiagnosed in the early stage. Because the nasopharynx is concealed, it lacks specific symptoms in the early stage, and the rich lymphatic vessels in the nasopharynx provide convenient conditions for cancer cell metastasis. However, it does not mean that there is nasopharyngeal carcinoma. The director of the Department of Otolaryngology-Head and Neck Surgery in a hospital pointed out that it is actually very simple to distinguish the cancerous "bloodsucking nose": the bleeding caused by dryness of the nasal cavity or nasopharynx is often short-lived, while the bleeding of nasopharyngeal carcinoma is repeated and persistent, showing aggravation, accompanied by tinnitus, hearing loss, ear blockage and other symptoms. At this point, as long as you go to the hospital for a nasopharyngoscopy, you can make a judgment at a glance. In addition, if there is a rapidly increasing mass in the neck, it may also indicate nasopharyngeal carcinoma. Because the internal structure of the nose is complex, and the lymphatic vessels in the nose are like a path leading to the outside world, this makes cancer cells close to the back of the earlobe of the neck, forming cervical lymph node enlargement. Director Huang said that if the lump grows to the size of a quail egg in a short time, it is best to go to the hospital for examination in time. Another neglected symptom of nasopharyngeal carcinoma is migraine. The doctor warned that if the above symptoms are accompanied by headache, cancer cells may have metastasized to the brain. Early headaches are generally intermittent, and late headaches are persistent and severe. At this time, patients can't just go to the neurology department to "treat headaches." It is best to take a picture of the cat's skull base or scan it with CT. It should be noted that although the medical community has not proved that persistent rhinitis can cause nasopharyngeal carcinoma, it does not mean that rhinitis has nothing to do with nasopharyngeal carcinoma. Epstein-Barr virus is one of the causes of nasopharyngeal carcinoma, which can also cause upper respiratory tract infection and then appear rhinitis symptoms. Therefore, it is best for patients with rhinitis to go to the hospital for EB virus serum examination in order to find cancer early. "Now, because the publicity of this disease is in place, Foshan citizens' vigilance against nasopharyngeal carcinoma has increased. Some patients even think that they have nasopharyngeal cancer because of dry nosebleeds. " Feng Huiling, deputy chief physician of Otolaryngology Department of Foshan Traditional Chinese Medicine Hospital, said. Phenomenon 1: Blood in sputum. Feng Huiling said that bleeding is a common manifestation of nasopharyngeal carcinoma in the early stage, but this kind of bleeding is mainly manifested by blood in sputum after nasal inhalation, which often occurs after getting up in the morning, and nosebleeds are sucked back from the mouth, and there is almost no blood. When the tumor is necrotic and ulcerated, there will be more bleeding and the nose will smell bad. Dr Chan Sarah, director of the Department of Otolaryngology, Foshan Second People's Hospital, also pointed out that early nasopharyngeal carcinoma was easily misdiagnosed as rhinitis due to frequent nasal congestion. Phenomenon 2: Symptoms in the ear It is reported that at present, the public is very sensitive to nosebleeds, but it is easy to ignore other "clues" about nasopharyngeal carcinoma. Dr. Feng Huiling pointed out that there is an eustachian tube between the human nasopharynx and the middle ear cavity, which can adjust the pressure in the middle ear cavity and keep the pressure inside and outside the tympanic membrane balanced. Nasopharyngeal carcinoma is easy to occur near the opening of eustachian tube. Cancer compresses the opening of eustachian tube, causing obstruction and causing symptoms similar to secretory otitis media. "If you find blood in the sputum or a lump in the neck, it is already in the middle and late stages. The earliest symptoms of patients we found in clinic are ear symptoms. This should remind the public in particular. " Feng Huiling said. Because the tumor grows in different locations, it may also show the symptoms of other neighboring organs. Patients with nasopharyngeal carcinoma tend to be younger. It has been proved by medicine that the incidence of nasopharyngeal carcinoma has family aggregation. Dr. Chan Sarah, director of the Department of Otolaryngology, Foshan Second People's Hospital, is doing a project funded by the National Natural Fund, which is to dynamically observe the families of patients with nasopharyngeal carcinoma, check EB virus, nasopharynx and proteome of high-risk groups every quarter, and take intervention measures for the families. Preliminary research shows that the incidence of nasopharyngeal carcinoma tends to be younger, from the high incidence age of 40~60 years old to the young people around 30 years old, and both men and women can get sick. In addition, people with qi deficiency constitution in nasopharyngeal carcinoma family are more likely to get sick, showing fatigue, weakness and pallor. Liang Guiwen, an attending Chinese physician in the Oncology Department of Foshan Hospital of Traditional Chinese Medicine, also pointed out that Chinese medicine believes that nasopharyngeal carcinoma is caused by visceral dysfunction, internal injuries, positive energy, seven emotions and six lewdness, and evil toxin taking advantage of it, leading to lung heat overflow, or liver and gallbladder heat toxin, or phlegm-fire mutual junction. Finally, phlegm-heat stasis toxin accumulates in the nasal orifices, blocking the meridians, and becomes nasopharyngeal carcinoma swelling for a long time. Eating more foods containing copper and selenium can prevent nasopharyngeal carcinoma. According to the epidemiological study in Hong Kong, a high incidence area of nasopharyngeal carcinoma, eating foods containing more ammonium nitrite such as salted fish and pickles will increase the risk of nasopharyngeal carcinoma, especially for children who start eating salted fish and pickles after weaning. Chan Sarah pointed out that the key to prevent nasopharyngeal carcinoma is to change bad eating habits and eat as little canned food, pickled products and smoked food as possible. Trace element copper in food can block ammonium nitrite, and it is easy to cause cancer when selenium content is insufficient. The public can eat more copper-rich egg yolk, shells and black fungus, as well as selenium-rich beans and sesame seeds. In addition, drinking green tea regularly can also prevent nitrosamines from being synthesized in the body; Grapes, tomatoes, white radish, garlic, mushrooms, barley and other things also have anti-cancer effects.
