Everybody is good, I am lung tumor, the lung tumor that usually people place says is lung cancer commonly, everybody hears this word, can feel all over tremble, letting a person is very afraid, what is that lung cancer?
Primary lung canc (lung cancer) is a malignant tumor originate from bronchial mucosal epithelium and alveoli, which can be divided into non-small cell carcinoma and small cell carcinoma. There are two main types of NSCLC: adenocarcinoma and squamous cell carcinoma. Lung cancer is not infectious, but has a certain degree of familial aggregation and genetic susceptibility. The current situation is that most of the lung cancer patients have distant metastasis at the first visit, mainly middle-aged morbidity, and there is a trend of gradually younger. Lung cancer is the malignant tumor with the highest morbidity and mortality in China, which causes serious losses and economic burden to society and families.
What are the symptoms of lung cancer?
Cough: the most common, more than 50% of patients have cough symptoms at the time of diagnosis, usually showing irritant cough, sometimes obvious cough at night or when lying down;
Hemoptysis: 25% to 40% will have symptoms of hemoptysis. Bloody sputum is the most common, and massive hemoptysis is rare.
Expiratory dyspnoea: Decreased alveolar area, central lung cancer obstructing or metastatic lymph nodes compressing large Airways, atelectasis, obstructive lung; Inflammation, pleural effusion, pericardial effusion, pneumonia, etc.
Fever: necrosis of tumor tissue, secondary pneumonia;
Primary tumor invades adjacent organs and structures: chest pain, hoarseness, chest distress, tachycardia, etc.
Distant metastasis of tumor: It can cause clinical signs of corresponding organs, and the most common is headache, nausea and vomiting caused by metastasis of central nervous system. Bone metastasis has more severe and progressive pain symptoms.
Lung cancer is not infectious, but has a certain degree of familial aggregation and genetic susceptibility. The current situation is that most patients are in local advanced or advanced state at the time of initial diagnosis, and the treatment effect is poor. Therefore, it is recommended that patients stay away from carcinogenic environment, such as smoking cessation, avoiding occupational environmental contact, air pollution, etc. At the same time, regular physical examination should be carried out to achieve early detection, early diagnosis and early treatment.
Smoking cessation is an important way
to reduce the risk of lung cancer.
Because the morbidity of lung cancer is insidious and the early symptoms are not typical, it is difficult to achieve the goal of “early diagnosis” through early symptoms. But if the following symptoms occur, we must pay attention to them:
1. Cough. It is characterized by irritating dry cough and often lasts for a long time. If combined with hemoptysis, especially with blood in sputum, they should go to the hospital as soon as possible for further examination. Lung cancer is highly suspected in long-term smokers with bloody sputum.
2. Chest distress and chest pain. The degree of pain is severe and the position is relatively fixed.
3. Fatigue, weight loss, low fever, bone and joint swelling and pain, etc.
Lung cancer is
caused by many factors, in daily life, how can we do a good job of lung protection? Shao Kang said that first of all, we must quit smoking. Quitting smoking is the most effective way to reduce the risk of lung cancer. The earlier we quit smoking, the greater the benefit. Second, we should turn on the lampblack machine when cooking, do a good job of ventilation, and reduce the pollution of kitchen fumes. Third, we should strengthen the occupational protection of the workplace. Fourth, we should use environmentally friendly materials for home decoration. Fifth, we should actively treat chronic lung diseases. Sixth, we should have regular physical examinations. “For people over 45 years old with a family history of lung cancer, the risk of cancer is higher, regular screening is particularly important, ‘early detection, early diagnosis, early treatment’ is the biggest secret to prevent and treat lung cancer.” “Care for life and prevent cancer scientifically!”
