The incidence rate of lung cancer remains high, and many patients are already in advanced stage when they visit the doctor, losing the best chance of treatment. Therefore, we emphasize again the early detection of tumors, especially the early detection of lung cancer is more important. Lung cancer is asymptomatic in many patients and it is difficult to detect it at an early stage, so regular medical checkups should be conducted. Many people don’t pay attention to the annual physical examination organized by the unit, and some people always think that they have no physical discomfort and neglect the physical examination. Each of us should give ourselves to cherish our life. There are many early symptoms of lung cancer, here are some common symptoms for your reference:. Coughing, coughing up sputum, chest tightness, breath holding, blood in sputum, coughing up blood, fever, chest pain, enlarged supraclavicular lymph nodes, skin changes, endocrine disorders, now there are many young patients with lung cancer, don’t think that you don’t pay much attention to medical checkups if you are not too old, lung cancer tends to be younger now, and many young patients are already in advanced stage when they are diagnosed, and the younger they are, the higher the malignancy degree is, and the more rapid the development is. People who have been under environmental pollution for a long time or have a family history of tumor should have regular checkups, such as smoking a lot for a long time, inhaling second-hand smoke, and having a poor working and living environment. With the advancement of medicine, we can also find some early lung cancers by testing tumor markers. There are also some patients who have found early tumors in lungs, but due to the lack of symptoms, they do not dare to admit the reality of lung cancer, and instead of treating it in regular hospitals, they seek for some kind of partial remedies and don’t believe in the scientific method, so that such patients delayed the precious time of treatment. Therefore, it is recommended that everyone should pay attention to medical checkups and cherish life!
