What are the early symptoms and precursors of lung cancer?

Cough, chest tightness and shortness of breath, coughing up sputum, blood in the sputum, and low-grade fever, this symptom may be a manifestation of lung cancer, and it must be checked in time, so as to avoid delay**.

Patients with lung cancer may present with cough, coughing up blood, shortness of breath, dyspnea and other discomforts, which are often mistaken for a cold or pneumonia after the onset of fever, but antibiotics cannot relieve the symptoms. When the tumor invades the pleura or bone, there is severe pain in the corresponding area. When a tumour involves lymph nodes, lymph nodes in that area become swollen.

The early symptoms and precursors of lung cancer, mainly cough, sputum production, hemoptysis, chest pain, chest tightness, shortness of breath, and coughing up blood is a very typical symptom.

In general, after the onset of central lung cancer, coughing up blood will appear in the early to middle stages, but the amount of coughing up blood is not large, and the texture is bright red or mixed with foam. This condition occurs because the surface of the tumor is rich in blood vessels, and coughing can cause superficial damage, which can lead to the rupture of blood vessels;

Feeling unwell, aching, diarrhea. Breathing pain is often felt as a sign of pneumonia lung cancer.

Often coughing, sometimes coughing up blood, chest pain, abnormal breathing, and low-grade fever.

The early symptoms and precursors of lung cancer are mainly cough, sputum production, hemoptysis, chest pain, chest tightness, and shortness of breath, among which coughing up blood is a very typical symptom. If the tumor is relatively small, localized, and has not spread, lung cancer patients are in the early stage of lung cancer at this stage. If it can be detected in time, the tumor cells can be completely removed through surgical resection, and the rate of patients with early lung cancer is relatively high.

There will be symptoms of cough, fever, blood streaks in the sputum of the cough, symptoms of chest tightness, shortness of breath, and appetite will be affected, and the whole person will become very thin.

I feel symptoms of weakness in the limbs, symptoms of hotheadedness, symptoms of loss of appetite, symptoms of lack of sleep, and symptoms of lung pain.

Lung cancer is a kind of malignant tumor, the harm to patients is very great, when suffering from lung cancer, patients will have some signs in the early stage of the body, in the early stage of lung cancer, patients will have chest, shoulder, back pain, cough and hemoptysis symptoms, when these symptoms appear, it is necessary to pay attention.

In recent years, the incidence and mortality of lung cancer have been on the rise, so understanding the early symptoms of lung cancer can allow patients to carry out the disease in a timely manner and prevent the rapid deterioration of the condition. Now, let's take a closer look.

1. Chest, shoulder and back pain.

In the early stage of lung cancer, patients will have symptoms of chest, shoulder, and back pain, and if the patient's lung cancer grows on the tip of the lung, it will invade the neuromuscular, bone joint, pleura and other parts, which will cause patients to have chest, shoulder, and back pain in the early stage. In addition, if the nerves in the patient's arm are compressed, it is easy to cause pain in the patient's arm.

When patients have this symptom, they must go to the hospital for examination in time, and do not eat some casually, cough and anti-inflammatory drugs to perfunctory.

3. Hemoptysis. In the early stage of lung cancer, patients will also have hemoptysis, which is an early symptom caused by cancer cells in the patient's body that damage the patient's blood vessels. Many patients will find blood streaks in the protruding sputum of their cough.

Therefore, the diagnosis of lung cancer must be made with the help of various special tests.
