What are the typical symptoms of early lung cancer? Five typical symptoms of early lung cancer

Any disease is difficult to detect at the beginning, but as time goes by, the disease will become more and more serious. Lung cancer is also difficult to detect at the beginning. By the time we find it, it is too late. So what are the typical early symptoms of lung cancer?

(1) Cough:

What are the typical early symptoms of lung cancer? The first is cough, which is the most common and typical symptom, and about 2/3 of patients have this symptom. It can be a mild dry cough or a severe cough, with varying amounts of sputum. However, in patients with chronic long-term coughs, once the nature of the cough changes, or the frequency changes or the cough occurs at night, be alert to lung cancer. Continuous and uncontrollable coughing is one of the most painful symptoms of lung cancer.

(2) Extrapulmonary and intrathoracic manifestations:

Secondly, the early symptoms of lung cancer are usually manifested outside the lungs and inside the chest. A series of chest manifestations can occur due to tumor invasion of the pleura, chest wall, mediastinal organs, and intrathoracic nerves. Tumor invasion of the pleura can cause breathing pain and pleural effusion (ie, pleural effusion). Bloody pleural effusion indicates a poor prognosis. If malignant tumor cells are found in the pleural effusion, the opportunity for surgery will be lost. Tumor involvement in the mediastinum is mostly caused by mediastinal lymph node metastasis, and a few are direct invasions.

(3) Manifestations of extrathoracic metastasis:

What are the early symptoms of lung cancer and what are the manifestations of extrathoracic metastasis? Experts say that lung cancer often metastasizes along lymphatic vessels and blood vessels, and metastases to cervical lymph nodes, liver, adrenal glands, bones, kidneys and brain are common. Nearly 15% of patients have metastatic lesions as the earliest manifestation, and blood-borne metastasis is the most common in adenocarcinoma and small cell lung cancer.

(4) Non-metastatic manifestations outside the chest:

Only 2% of patients may have non-metastatic manifestations outside the chest, but the symptoms are complex, involving multiple systems, and the etiology is unclear. Common manifestations include skeletal manifestations, such as clubbing of fingers (toes) and osteoarthritis, neuromuscular manifestations, such as myopathy, peripheral neuropathy, cerebellar degeneration, etc.

(5) Systemic manifestations:

The systemic manifestations of lung cancer are the same as those of other malignant tumors, including anorexia, weight loss, fatigue, and finally cachexia.

Many diseases in life seem far away from us, and we always think that they will never happen to us. In fact, we must not have this fluke mentality. It is recommended that everyone learn more about lung cancer, so that we will not be unaware of it when lung cancer has already occurred, and finally cause tragedy.
