In recent years, the incidence of lung cancer has increased. Seeing more cases of lung cancer, some people call lung cancer a countdown race to life, which does make sense. Because the early stage of lung cancer is very insidious, and it develops very rapidly, it often takes a few months to miss the treatment period.
Many people have a cough in the early stage of lung cancer. Because cough is so common in life, most people often don’t realize that their cough is caused by lung cancer, so it is easy to miss the opportunity to find out. .
Ordinary coughs are mostly caused by upper respiratory tract infections or lung infections, such as common flu, Allergic rhinitisInflammation such as bronchitis, pneumonia, etc. will cause the lungs to produce sputum and cause coughing. Usually the inflammation is eliminated and the cough will cease if there is no sputum.
There are four reasons why lung cancer can cause cough:
①The tumor cells in the bronchial lumen secrete mucus, which stimulates the tracheal mucosa.
②Bleeding on the tumor surface, blood irritation to the bronchial mucosa can also cause coughing.
③If the tumor is relatively large, it will block the lumen of the bronchus, causing obstructive pneumonia and coughing.
④The tumor invades the surrounding tissues of the lung, causing chest tightness, pleural fluid, and irritating cough.
In addition, coughs caused by lung cancer will also have the following characteristics: Most of them are paroxysmal irritating coughs, no sputum, and sometimes hemoptysis, and they will not heal for a long time.
So, if hemoptysis occurs and the dry cough does not heal for more than three weeks,It's about to attract attention.
Professor Zhi Xiuyi, chief expert of thoracic surgery in Xuanwu Hospital mentioned in an interview, The key to preventing lung cancer is to prevent the "three hazes and five gases." The "three hazes" refer to smog, haze and inner haze. The "five gases" refer to air pollution, kitchen fumes, sultry, smoke, The smell of decoration materials.
In short, the following points can avoid the "three haze and five qi" and achieve the effect of preventing lung cancer.
1. Refuse to smoke, avoid second-hand smoke
Prevent lung cancer, firstOne thing to stay away from is cigarettes. A large number of studies have shown that smoking has a high carcinogenic rate and is the main cause of lung cancer. Not only the smoker himself, but also the second-hand smoke released by the smoker will increase the risk of lung cancer in people around him.
2. Keep the kitchen ventilated
In addition to smokers, another high-incidence group of lung cancer is chefs and housewives. Both types of people need to work in the kitchen for a long time, and must be exposed to more oil fume than ordinary people, and oil fume is also a typical carcinogen. Therefore, people who need to be in contact with the kitchen for a long time must buy a high-quality range hood and use it fully, and keep the kitchen ventilated and convective. If possible, try to avoid cooking methods such as stir-frying, grilling, frying, etc. to reduce oily fumes.
3. Wear a mask when you go out.
The damage of air pollution to the lungs It is also no small matter. People who have been out for a long time inhale too much airborne particles, which will greatly increase the possibility of lung cancer. Therefore, it is recommended to wear masks frequently when you go out, especially for people who often work outdoors. Minimize going out in the haze weather and try to avoid lung damage.
4, Properly vent, don’t get sulking
Introverted people are more likely to get cancer, especially lung cancer, than optimistic and cheerful people.
Sulking, depression and anxiety are bad moods and high-risk factors for lung cancer. If a person is in a state of tension and depression for a long time, the body’s immunity will decline, which may induce cancer cell mutations. In addition, the survival time of lung cancer patients who often have bad moods in clinical practice will be shortened.
5. Ventilate the new house before moving in after renovation
Don’t move in a hurry after the house is renovated. Put it aside, ventilate, and wait until the benzene and formaldehyde reach the standard before moving in. Because the materials used in house decoration may contain harmful gases such as benzene and radon, the human body will increase the incidence of cancer after inhalation.
