Symptoms of invasive lung cancer

Symptoms of invasive lung cancer include cough, chest pain, dyspnea, coughing up blood, and weight loss. If you experience these symptoms, you should seek medical attention immediately. Early diagnosis and treatment are crucial to improving survival rates.

1. Cough is one of the most common early symptoms of invasive lung cancer. Cough may last for weeks or even months and usually does not resolve on its own. The nature of the cough may gradually change from a dry cough to a wet cough with sputum. For patients with long-term cough, especially smokers, chest imaging examinations should be performed as soon as possible to rule out the possibility of lung cancer.

2. Chest pain is another common symptom, usually manifested as dull pain or pressure in the chest. Chest pain may be related to the tumor invading the chest wall or pleura, or it may be related to the tumor compressing surrounding tissues or nerves. The location and nature of chest pain may vary depending on the location and size of the tumor, and some patients may feel that the pain is aggravated when taking a deep breath or coughing.

3. Dyspnea is a late-stage symptom of invasive lung cancer, usually related to tumor obstruction of the airway or pleural effusion. Patients may feel short of breath, especially after activities or when lying down. The degree of dyspnea may worsen as the tumor progresses, and in severe cases may make patients unable to carry out daily activities.

4. Hemoptysis is one of the typical symptoms of invasive lung cancer, usually manifested as blood in sputum or hemoptysis. Hemoptysis may be related to tumor invasion of blood vessels or bronchial mucosa. The amount and frequency of hemoptysis may vary depending on the size and location of the tumor. A small amount of hemoptysis may be an early symptom, while a large amount of hemoptysis may indicate tumor progression.

5. Weight loss is a common systemic symptom of invasive lung cancer, which is usually related to the tumor consuming nutrients in the body or the patient's loss of appetite. The degree of weight loss may vary depending on the progression of the tumor and the patient's nutritional status. Some patients may experience significant weight loss in a short period of time.

For patients with the above symptoms, it is recommended to seek medical attention as soon as possible for detailed examinations, including chest X-ray, CT scan, bronchoscopy and pathological biopsy. Early diagnosis and treatment are crucial to improving the survival rate of invasive lung cancer. Treatment methods include surgical resection, radiotherapy and chemotherapy, and the specific treatment plan should be formulated according to the patient's condition and physical condition.

The symptoms of invasive lung cancer vary. Early symptoms may not be obvious and are easily overlooked. For high-risk groups, such as long-term smokers and those with a family history of lung cancer, regular lung cancer screening should be performed for early detection and treatment. If symptoms such as cough, chest pain, dyspnea, coughing up blood, and weight loss occur, medical attention should be sought promptly. Early diagnosis and treatment are crucial to improving survival rates.
