Symptoms of lung cancer Cough is the most common symptom, with cough as the first symptom accounting for 35% ~ 75%. Cough caused by lung cancer may be related to intrathoracic complications such as changes in bronchial mucus secretion, obstructive pneumonia, pleural invasion and atelectasis.
For patients who smoke or suffer from chronic bronchitis, if the degree of cough increases, the frequency changes and the nature of cough changes, such as high-pitched metallic sound, especially the elderly, we should be highly alert to the possibility of lung cancer.
Blood in sputum, hemoptysis and blood in sputum are some common symptoms of lung cancer. Time is intermittent or continuous. Tumor invasion and destruction of bronchial mucosa capillaries or tumor tissue vascular rupture can lead to blood in sputum, mostly fresh bloodshot or blood spots in sputum, which appear intermittently or repeatedly. Early lung cancer rarely causes hemoptysis. Hemoptysis is more likely to attract patients' attention than other symptoms, so that further examination can find early lung cancer.
Chest pain, with chest pain as the first symptom accounting for about 25%. Often manifested as irregular dull pain or dull pain in the chest. In most cases, peripheral lung cancer invades parietal pleura or chest wall, which can cause severe intermittent pleural pain. If it continues to develop, it will turn into constant pain.
Mild chest discomfort that is difficult to locate is sometimes related to central lung cancer invading mediastinum or involving blood vessels and peripheral bronchial nerves, while 25% patients with malignant pleural effusion complain of chest pain. Persistent and severe chest pain is not easily controlled by drugs, which usually indicates extensive pleural or chest wall invasion. Persistent pain in the shoulder or chest and back suggests the possibility of tumor invasion near the mediastinum in the lung lobe.
Chest tightness and shortness of breath are the first symptoms of about 10% patients, which are more common in central lung cancer, especially in patients with poor lung function. Because the early symptoms of lung cancer are hidden and difficult to be found, most early lung cancer is often found by accident when patients take pictures or ct examinations in hospitals due to physical examination, car accidents, trauma and other reasons.
What causes chronic obstructive pulmonary disease? Lung cancer is a common malignant tumor, and about 1% of patients with chronic obstructive pulmonary disease will suffer from lung cancer every year. Many patients with chronic obstructive pulmonary disease regularly take medicine in the outpatient department, but turn a deaf ear to the doctor's advice on lung function examination, and finally get lung cancer.
Smoking is considered as an important risk factor for lung cancer. The more you smoke, the longer you smoke, and the earlier you start smoking, the higher the mortality rate of lung cancer. The risk of lung cancer of smokers gradually decreases with the extension of years of quitting smoking, and it is similar to that of non-smokers after quitting smoking 15 years. Passive smoking can also easily lead to lung cancer.
Occupational carcinogens, there are many occupations now, and some occupations will come into contact with some carcinogens, which will lead to lung cancer. These carcinogenic factors include asbestos, inorganic arsenic compounds, dichloromethyl ether, soot, tar and so on.
Air pollution, air pollution includes indoor small environment and outdoor big environment pollution. Such as indoor passive smoking, fuel burning and carcinogens that may be produced during cooking. Carcinogens exist in automobile exhaust, industrial exhaust and highway asphalt in cities, among which benzopyrene is the main one.
Ionizing radiation, high dose of ionizing radiation can lead to lung cancer, and different radiation rays have different effects. For example, Hiroshima, Japan releases neutrons and instrument rays, while Nagasaki only emits rays. The former is more prone to lung cancer than the latter.
How to prevent lung cancer, control and ban smoking? The mechanism of smoking causing lung cancer has been clearly studied, and epidemiological data and a large number of animal experiments have completely proved that smoking is the number one killer of lung cancer. Both ourselves and society should take action.
Improve the ventilation environment in the workplace, reduce the concentration of harmful substances in the air, transform the production process and reduce the generation of harmful substances. Workers in dust polluted environment should wear masks or other protective masks to reduce the inhalation of harmful substances.
There are also certain taboos in diet. Diet should be high in protein, comprehensive in nutrition, high in vitamins, low in fat and salt, and avoid smoking and alcohol; Reduce the intake of spicy food: onion, garlic, ginger, pepper, etc. ; Eat less hot food such as frying and barbecue. You should eat some fresh vegetables and fruits rich in nutrition and vitamins. Always keep cheerful and upward, and don't be unhappy about trifles.
Pay attention to the prevention of lung cancer. Whether it is lung cancer or other kinds of cancer or other diseases, the best prevention method is to have a positive attitude and lifestyle, participate in appropriate exercise regularly, enhance physical fitness, have regular physical examinations, and know your physical condition in time.
What fruit is good for lung cancer? Kiwifruit can protect the intercellular barrier, eliminate the ingested carcinogens, and prolong the survival of lung cancer patients, especially for lung cancer patients after radiotherapy.
Resveratrol contained in grapes and grapes can prevent normal cells from becoming cancerous and inhibit the spread of malignant cells.
Strawberry Strawberry contains ellagic acid, which can protect the body from carcinogens and has a certain anti-cancer effect. The effect of strawberry on promoting fluid production and quenching thirst is very beneficial to relieve the radiotherapy reaction and symptoms of lung cancer patients.
Banana and banana extracts have obvious inhibitory effects on aflatoxin B 1 and other carcinogens. Banana contains magnesium and potassium, which has certain anti-cancer and anticancer effects.
Apricot is suitable for all kinds of cancer patients. According to research, Rouge Red Apricot is a fruit rich in vitamin B 17, which is an extremely effective anticancer substance and can kill cancer cells.
