What are the early symptoms of lung cancer? 6 early symptoms of lung cancer

What are the early symptoms of lung cancer? When it comes to lung cancer, many people think that this disease is very serious. Because people don’t know much about this disease, they often can’t find the disease in time. Even if symptoms appear, they can’t find it in time. So, what are the early symptoms of lung cancer?

A small number of lung cancer patients are asymptomatic and are only discovered during routine physical examinations and chest imaging examinations. The rest of the patients may show more or less lung cancer-related symptoms. Common symptoms of lung cancer include cough, hemoptysis or blood in sputum, chest pain, chest tightness, shortness of breath, etc., as well as mass shadows on X-rays.

(1) The early symptoms of cough are usually an irritating dry cough with little or no sputum. When accompanied by infection, the sputum will increase and become mucopurulent.

(2) Bloody sputum or hemoptysis: When the tumor grows into the lumen, there may be intermittent or continuous blood in the sputum. Surface erosion and damage to large blood vessels may cause massive hemoptysis.

(3) Shortness of breath or wheezing When the tumor grows and compresses the bronchi or blocks the airways, breathing difficulties, shortness of breath, wheezing, and occasionally wheezing may occur.

(4) Chest pain is difficult to describe or is dull pain, which is usually caused by invasion of tumor cells or inflammation affecting part of the pleura or chest wall.

(5) Fever Most fevers are caused by obstructive pneumonia caused by tumors.

(6) Weight loss and emaciation are common manifestations of malignant tumors.

Extrathoracic metastasis of lung cancer is relatively easy to identify. Lymph node metastasis is common in supraclavicular lymph nodes, which are characterized by fixed, hard, gradually enlarged, and increased number of lymph nodes, and are usually painless. When the tumor directly invades the pleura or pericardium, it can cause pleural effusion and pericardial effusion. Metastasis to the bones can cause bone pain and pathological fractures. Metastasis to the central nervous system can cause intracranial hypertension, headache, nausea, vomiting, mental abnormalities and other symptoms.
