Early signs of lung cancer

higher incidence of lung cancer in our country, seriously affecting the patient's life and health. What about the early signs of lung cancer, so early detection in order to seek to apply to surgery-based comprehensive treatment of lung cancer therapy the key to good results.
First, the early signs of lung cancer
Early symptoms of lung cancer, the most easily detected, and lung disease is very clear. Experts tell us that the clinical manifestations of lung cancer and cancer of the location, size, whether the oppression, invasion of adjacent organs and metastasis and so closely related.
Shortness of breath,广州肿瘤医院, pneumonia, cancer caused by obstruction, atelectasis, pleural effusion, such as diffuse alveolar disease can cause.
Cough, mostly irritating cough. Early symptoms of lung cancer is cough, is characterized mainly paroxysmal irritating cough, cough do not have the feeling of the net, usually no or only a small amount of white foam sputum sputum, purulent sputum may be secondary infection. Such as anti-inflammatory treatment after 2 weeks without improvement, should be alert to the possibility of lung cancer. Or on the basis of the original chronic cough cough nature of the change, even accompanied by Another warning of lung cancer is repeated a small amount of intermittent bloody sputum, or blood stained sputum. In addition, there thoracodorsal pain, chest tightness, fever and other symptoms.
Recommended in patients with these symptoms, go to the hospital for scientific examination, early detection and early treatment of lung cancer should be as early as the difficulty of lifting the pain of illness.
Common signs of early lung cancer early lung cancer generally does not produce symptoms, so called asymptomatic phase, the short is a few months or as long as several years, vary, patients rarely seek medical treatment at this time, so the clinical difficult to find, but some early symptoms of lung cancer dry cough, chest pain, fever, coughing up blood and other general respiratory symptoms, these symptoms with colds, bronchitis, pneumonia and other diseases to be confused, unable to draw the attention of patients. In addition to those symptoms, because lung cancer, like other nerve compression, the majority of the external signs will also be seen, patients and their families should pay more attention, and timely treatment.
Cancer violation of the vagus nerve can speed up heart rate, cardiac conduction system violation can cause arrhythmia, pericardial effusion can produce violations of the pericardium, there constrictive pericarditis symptoms.
1, through the lymphatic metastasis of lung cancer can be seen when the corresponding group of lymph nodes and adjacent parts of the corresponding parts of the pressure symptoms. Metastasis to the brain through the blood, bone, liver and other parts of the time, there are corresponding signs.
2, other signs, limb pain or enlargement clubbing, multiple neuritis, myasthenia gravis, Cushing's syndrome and male breast hypertrophy, mental disorders.
3, thick and greasy tongue coating with a multi, yellow tongue coating, followed by exfoliation, tongue cracks and prick were significantly increased. Sublingual veins exposed, large collaterals filling, small varicose collaterals, sublingual ecchymosis petechiae increased significantly.
4, looking, looking more common in patients with lung cancer, pale, dull, flushing, purple, red, such as makeup, facial crab claw pattern, dull complexion and other abnormalities, especially the Ministry of cheeks significant. Especially the zygomatic clinical stage of the crab claw pattern of increase as aggravated.
5, the limitations of wheezing: song for the unilateral nature of the limitations of asthma, especially in the inspiratory phase of wheezing, cough does not disappear, the early signs of lung cancer, but it was too short, easily overlooked.
6, oppression or violation of the recurrent laryngeal nerve lymph node metastasis (left more common) when a hoarse voice. Ipsilateral mediastinal check laryngoscopy vocal cord paralysis.
7, when the cancer pressure to catch up with the superior vena cava, common in the upper right Ye cell carcinoma, head and upper extremity venous obstruction, resulting in the head and face and upper body edema and venous engorgement, stasis (ie, superior vena cava compression syndrome).
8, apex of lung cancer called Pancoast tumor, usually caused by ipsilateral cervical sympathetic nerve compression miosis. Upper eyelid ptosis, enophthalmos, eye crack is small, less sweat and other frontal Horner syndrome.
9, brachial plexus compression caused by the ipsilateral shoulder and arm pain, can not be flattering, shoulders and fingers radioactive pain and paresthesia, muscle atrophy.
10, oppression esophagus caused by swallowing difficulties, or even a bronchial-esophageal fistula, leading to lung infections, severe airway pressure can suffocate.
11, oppression caused by the ipsilateral phrenic nerve and diaphragm paralysis increased, X-ray shows the sick side of the diaphragm bradykinesia, reduced nasal breathing with contradictions.
12, the tumor close to the pleural effusion can cause a reaction, often produces bloody invasion and pleural effusion.
Two, four lung disease and lung cancer is easy to confuse
Pneumonia
Bronchial pneumonia is generally more acute onset, fever and other more obvious symptoms of infection by antibiotic treatment the symptoms quickly disappeared, the lung disease is also rapidly absorbed. However, if the absorption is slow or recurring inflammation, should be done in-depth examination.
Pneumonia is an infectious disease can be cured by antibiotics and other treatment. However, if a part of recurrent pneumonia, lung cancer should be aroused our vigilance.
Lung cancer is lung cancer, the general performance of the lung mass,肿瘤医院, but mass is very small, imaging studies may not check out. Any foreign body or endobronchial tumor obstruction, even if it is incomplete obstruction, can lead to local inflammation of lung tissue, that is pneumonia. If a site of recurrent pneumonia, should be wary of whether it is lung cancer.
Therefore, if there is cough, recurrent pneumonia in the same position, it is strongly recommended for bronchoscopy, the early detection of lung cancer
Abscess
Necrosis of the central part of the lung, cancer of the cavity formed when liquefied, X-ray findings easily confused with lung abscess, but cases of lung abscess is often a history of aspiration pneumonia. Obvious acute signs of infection, sputum volume, purulent, the smell. X-ray film over the wall thin, smooth wall surface with liquid, the lung tissue around the abscess or pleural often inflammatory lesions.
Tuberculosis
For middle-aged pulmonary tuberculosis patients, tuberculosis and other parts of the lesion showed massive shadow, after anti-TB drug treatment did not improve lung lesions, but increases the shadow or block segment or lobe associated with lung atelectasis, hilar shadow side widened, etc., should lead to the coexistence of tuberculosis and a high degree of suspicion of lung cancer, we must further do bronchoscopy and sputum cytology screening.
Asthma
Asthma and lung cancer may have a common pathogenesis, chronic inflammation can trigger asthma produce too many free radicals, highly reactive free radicals are the body's atoms or groups of atoms to the human body, oxidation of other substances, which not only damage the genetic material, but also can promote cancer formation and development. Female patients with asthma, should be vigilant, regular review. X-ray diagnosis of lung cancer is the most important means used should be receiving a check every six months, if the merger while other typical symptoms, should be confirmed by bronchoscopy, with a view to detect lesions, early diagnosis and improve survival.
Third, how early detection of lung cancer
Special emphasis on high-risk groups, there's the first one is the heavy smoking, family history and the second immediate family history of cancer there, especially a history of lung cancer, indicating that genetic resistance to the anti-cancer substances relatively poor. In addition there are exposed to occupational pollution, for example, then a radioactive contamination in the workplace or the chemical, physical, and so will lead to cell damage long-term work such as the workplace, and also we have to regularly check. Finally speaking, if irritating cough, cough nature, of course, everyone will cough are to be persistent dry cough, yet with bloodshot eyes, this should be particularly worried, go to the hospital to be checked. Other chest pain or chest discomfort, heavy smokers, and if it is just the introduction of several high-risk groups, also need regular checks. Early detection is the need for a pattern of regular physical examination, including chest perspective, blood tests, including other appropriate testing. This can detect early lung cancer, and timely treatment.
Early detection is divided into three levels. From roughly speaking, a country to early detection of cancer, the state high-risk groups, is relatively high in areas of lung cancer, lung cancer is relatively high in the screening of the population, which is the country's behavior. We, as Internet users, as people in the country doing this work, there are at least two things to do. First, we make a healthy people should insist on an annual physical examination, which is most important. Health examination per year, while stress is the lateral chest physical examination is very important, some netizens said before I have a physical examination, physical examination is over, just do chest, does not work. Second, only according to chest X-ray positive, according to a small piece, does not work. Should also do a standard chest radiograph and lateral areas where conditions permit, conditional units, qualified people, but also suggested a spiral CT, small price to receive the radiation is very low. Third, remind us of the heavy smokers, smoking more than 20 per day or more than 20 years, these recommendations every six months in non-smoking medical areas where conditions permit, the insurance people, and recommends low-dose CT, there are many center of the low-dose CT into the normal physical examination. We also do cancer-related subject matter are necessary to check. All in all, healthy people, smokers have respiratory symptoms, these residents should be wary of lung cancer, should pay attention to health checks and to the hospital to be checked.
Early lung cancer, should pay more attention, care and conditioning of science diet, follow the doctor's treatment of the arrangements to reduce the threat of lung cancer metastasis, healthy and happy life. In addition to early detection, early diagnosis, early treatment is key to improving lung cancer.
