Why is lung cancer mostly in the late stage? Pay attention to these three aspects

Many people are already in the late stages of lung cancer after they are diagnosed with it. This is because it takes time for lung cancer to take root in the body, and its symptoms are not very obvious. At the same time, if you do not have regular lung examinations, the tumor will take root in the body and cannot be detected. In addition, in the early stages of lung cancer, its symptoms are very similar to those of diseases such as tuberculosis, making it difficult to diagnose and prone to misdiagnosis.

When feeling unwell, many people will think that they can just bear with it and will not go to the hospital immediately. But many times, not going to the hospital for examination in time will lead to physical discomfort and cause malignant diseases. Especially for some lung cancer patients, there are no obvious symptoms in the early stage, they will only feel unwell, and when they go to the hospital, they are already in the middle and late stages. So why is lung cancer mostly in the late stage?
1. Why is lung cancer mostly diagnosed in the late stage?
1. Symptoms are not obvious <br/>Many people find that lung cancer is already in the late stage when they discover it. Because the carcinogenic factors in the body need to enter the lungs through the various immune layers of the human body, it takes a certain amount of time to break through the body's immune defenses. The development of cancer cells also takes time, so there are no obvious symptoms in the body after the onset of lung cancer. Only when cancer cells invade the affected area will obvious symptoms of lung cancer appear.
2. Not having regular lung examinations <br/>Many people ignore lung examinations during examinations. Since many people do not pay attention to daily examinations, lung cancer will occur in the body, causing the occurrence of lung cancer, especially for some high-risk groups, such as frequent smokers, who need to have a lung examination in time when they have coughs and chest tightness.
3. Misdiagnosis of the disease <br/>Since the symptoms of lung cancer are not very obvious, it is easy to be misdiagnosed as pneumonia or tuberculosis in the early stage. These are common diseases, so it is often too late to confirm the diagnosis.
2. Symptoms of lung cancer <br/>In order to better understand lung cancer, it is necessary to know the symptoms of lung cancer. After the onset of lung cancer, there will be obvious low-grade fever and cough. The tumor will block the bronchus, causing obstructive lung lobes to appear, and the degree varies. Those with milder symptoms will only have a low-grade fever, while those with severe symptoms will have a high fever. In addition, after the onset of lung cancer, there will also be coughing, most of which are irritating coughs, and there will be blood in sputum.
