Highest morbidity and mortality in the world The malignant tumor is still lung cancer, and the pathogenesis is not very clear. It is generally believed to be related to smoking and heredity. The early symptoms of lung cancer are not very significant, and most patients have reached the middle and advanced stage when they are diagnosed, missing the golden treatment period and reducing the five-year survival rate. Lung cancer doesn’t come quietly, but is often overlooked.

Lung cancer is difficult to detect in the early stage
Early stage Patients with lung cancer basically have no obvious symptoms, and they will not show obvious symptoms until the tumor has grown to a certain extent, that is, it has entered the middle and advanced stages. Clinical reactions such as cough, expectoration, chest tightness, shortness of breath, and even dyspnea are the reasons why lung cancer is in the middle and late stages as soon as it is discovered.
Although it is difficult to detect lung cancer early, it is not without trace.
Be careful of the following situations in the body
1. Cough Cough is the first symptom of lung cancer, and as the tumor gradually increases, it stimulates the bronchi mucous membranes, resulting in irritating cough, showing paroxysmal, even taking cough medicine has little effect.

2, Blood in sputumSome lung cancer patients have blood streaks in sputum, and sometimes cough up blood, because the tumor tissue has a rich blood supply, and severe coughing can easily cause blood vessels to rupture and bleed. If there is always blood in the sputum recently or a small amount of coughing up blood, it is necessary to go to the hospital for relevant examinations in time. 3. Hoarseness Many lung cancer patients may have mild or severe hoarseness, hoarseness is more sudden, and develops so rapidly that the voice disappears completely within a short period of time. There is no effect with conventional treatments.

4, Abnormal skin on both legs
From the point of view of traditional Chinese medicine, the lungs control the skin, and the reduction of lung function can weaken the breathing ability, resulting in insufficient oxygen content in the blood, hindered blood circulation, and unable to provide the skin or the skin. Mucosal tissue provides needed nutrients and oxygen, resulting in lightening of the skin and mucous membranes. If the skin of both legs is always found to be abnormal recently, and there is a history of smoking or exposure to second-hand smoke, it is necessary to go to the hospital as soon as possible for low-dose spiral CT screening. 5. Leg pain
Many lung cancer patients will have leg joint pain in the early stage, which is often mistaken for joint wear or degeneration. resulting in misdiagnosis or missed diagnosis. When lung cancer develops to the middle and late stages, the cancer cells can invade the bones and cause bone pain; as the cancer cells gradually increase, it is easy to cause traction pain and reflex pain.
Which types of people are at high risk of lung cancer?
1. Smoking and exposure to second-hand smoke Cigarettes contain thousands of chemical substances, including dozens of carcinogens such as polycyclic aromatic hydrocarbons, nicotine and tar, both active smoking and exposure to secondhand smoke can increase the risk of lung cancer.

2, Pulmonary tuberculosis patients Tuberculosis is a common chronic infectious disease, most of which occur in the lungs, and there may be residual tuberculosis lesions in the lungs. If left unchecked, it can gradually develop into lung cancer. 3. Family history of lung cancer Lung cancer has a certain genetic predisposition. If there is a lung cancer case in the immediate family, the risk of developing cancer is much higher than that of ordinary people. 4. Long-term exposure to harmful substances Workers who have been exposed to kitchen fumes for a long time, often exposed to asphalt, coking and gas, and have been exposed to asbestos and inorganic arsenic for a long time are all at high risk of lung cancer.
Do 6 things to avoid lung cancer
1. Say no to tobacco
According to existing research results, Smoking and exposure to secondhand smoke are important risk factors for lung cancer. And smoking also increases lung cancer mortality, with smokers 10 to 13 times more likely to die from lung cancer than non-smokers.
While quitting smoking is difficult, it is important to work hard. Studies have shown that even if lung cancer is diagnosed and treated with surgery, patients who quit smoking for a period of time have significantly lower postoperative complications and 30-day mortality than patients who have not quit smoking. 2. Let the range hood run for a while. The kitchen recommends choosing a range hood with sufficient horsepower, cleaning it regularly, and using cooking methods such as steaming when cooking. Turn on the range hood before turning on the fire, which can minimize harmful gases; if frying, stir-frying, etc. are used, you should also turn off the range hood after 3 to 5 minutes after turning off the flame strong>. 3. Stay away from air pollution as much as possible You can install air purifiers indoors, and eat more fruits and vegetables that nourish your lungs. 4. Don’t be sullen Cancer is closely related to the mental state. Being sulky and having a high psychological pollution index will affect the immune mechanism and make cancer an opportunity. Try to stay happy and open-minded and don’t get sulky about the little things. 5. Actively “clean” your lungs Every morning, noon, or before bed, go outside to fresh air and take deep breaths while slowly raising your arms, then coughing , so that the air is sprayed from the mouth and nose, and the phlegm is coughed up. Take a few normal breaths after each session, and stick to it every day to help keep your lungs clean. 6. Improve immunity Any disease is caused by an imbalance between resistance and immunity, and lung cancer is no exception. Appropriate intake of vitamin-rich fruits and vegetables in the usual diet, adherence to exercise, regular work and rest, etc., are very helpful to balance resistance and immunity.
