What are the specific symptoms of lung cancer?

What are the symptoms of lung cancer? Lung cancer refers to a malignant epithelial tumor of the lung. It originates from the bronchial epithelium, bronchial mucous glands, bronchiolar epithelium and alveolar epithelium, etc. It is called bronchial lung cancer, or lung cancer for short.

Common symptoms of lung cancer include cough, chest pain, hemoptysis, fever, etc., but they are not specific, so they are not conducive to early detection. Generally, symptoms of central lung cancer appear earlier and more obviously than those of peripheral lung cancer. The common symptoms are described below:

What are the symptoms of lung cancer? Symptoms caused by primary cancer Cough: It is the most common symptom, often manifested as an irritating dry cough that is not easily controlled by drugs. When secondary infection occurs, the cough is accompanied by mucopurulent sputum.

Hemoptysis: About half of lung cancer patients have this symptom, which manifests as persistent or intermittent repeated coughing of small amounts of blood or blood in sputum. When the cancer erodes the large blood vessels, it causes massive hemoptysis.

Shortness of breath, chest tightness, and shortness of breath: This is mostly caused by the growth of cancer at the opening of the trachea, blocking the airway. Lung cancer complicated by lung infection, a large amount of pleural effusion compressing the chest cavity in the late stage, and diffuse cancer in both lungs causing decreased lung function can all lead to shortness of breath symptoms.

Systemic symptoms: fever, weight loss, cachexia, etc.

What are the symptoms of lung cancer? Symptoms caused by local tumor spread Chest pain: When the tumor directly invades the pleura, ribs, and chest wall, chest pain occurs. When the tumor is near the pleura, it is mostly irregular dull pain or dull pain; when the ribs are invaded, the pain is relatively fixed and the tenderness point can be found; when there is uncontrollable severe pain, there is almost always extensive pleura or local chest wall invasion, and the prognosis is poor.

What are the symptoms of lung cancer? Difficulty in swallowing. Cancer invasion or compression of the esophagus can cause difficulty in swallowing, and may even erode and penetrate the wall of the tube, forming a bronchoesophageal fistula, leading to choking and coughing during eating and lung infection.

Hoarseness: Cancer metastasis causes enlargement of the mediastinal lymph nodes, compressing the recurrent laryngeal nerve (more common on the left side), which may cause hoarseness.

Superior vena cava compression syndrome: The tumor compresses the superior vena cava, causing obstruction of blood return, resulting in edema of the head, face, neck, and upper limbs, and distension of the veins in the anterior chest, causing headaches and dizziness.

Symptoms of distant metastasis of cancer Lung cancer patients are most likely to have distant metastasis to the brain, liver, and bones. Symptoms of brain metastasis include headache, nausea, vomiting, and difficulty in limb movement; symptoms of liver metastasis include anorexia, jaundice, pain in the liver area, ascites, etc., and abnormal liver function tests in hospitals; when metastasized to the bones, severe cases may experience local severe pain and even fractures. Common bone metastasis sites are the spine, ribs, skull, and bones.

Extrapulmonary manifestations A small number of patients will develop a group of extrapulmonary manifestations due to the ectopic endocrine effect of the tumor, also known as "paraneoplastic syndrome", such as bone and joint hypertrophy and clubbing, acanthosis nigricans, hyponatremia, adrenocortical hyperfunction, gynecomastia, myasthenia gravis, spinocerebellar degeneration, peripheral nerve degeneration, etc. Among the above extrapulmonary symptoms, bone and joint hypertrophy and clubbing are more common in my country.
