What are the key points for diagnosing central lung cancer? 4 key points for diagnosing this type of lung cancer

Central lung cancer is a relatively common tumor disease. Its onset is affected by many factors, such as smoking, ionizing radiation, air pollution and other dangerous environmental factors. At the same time, personal factors such as heredity and chronic lung diseases may also play a role. Clinically, symptoms such as irritating cough, coughing up blood or blood in sputum, and chest pain may occur.

Early diagnosis of central lung cancer is difficult, and most patients die within 5 years after diagnosis. If it can be diagnosed early and treated in time, the patient's symptoms will be significantly relieved and the survival time can be extended to a certain extent. However, many patients do not know the diagnostic points of central lung cancer. Let's learn about it today.

1. Central lung cancer is also a common lung cancer and respiratory malignancy, which is related to peripheral lung cancer. Central lung cancer refers to lung cancer masses mainly in the center of the hilum of the lung. Generally speaking, central lung cancer may be discovered late, and there is no chance of radical surgery. It requires comprehensive treatment such as radiotherapy and chemotherapy. If surgery is possible, it is usually a complete lung resection, which requires a relatively high physical condition of the patient and the prognosis may be poor.

2. The diagnosis of central lung cancer focuses on clinical symptoms, medical history and clinical examination. First, observe whether the patient has symptoms such as cough, blood in sputum or hemoptysis, dizziness, unsteady walking, subcutaneous nodules, etc.; check whether the patient has a family history of cancer and smoking history; finally, do clinical examinations, such as lung cancer tumor marker examination, chest CT to confirm the presence and location of lesions, head MRI, liver CT, bone scan to determine whether the tumor has metastasized, etc. Based on the results, diagnose the tumor and its stage, and determine whether surgery can be performed.

3. Lung cancer is related to smoking, air pollution and environmental factors. Genetic factors, family aggregation, genetic susceptibility, decreased immune function, metabolic and endocrine dysfunction may also play an important role in the occurrence of lung cancer. Many studies have shown that genetic factors may play an important role in people or individuals who are susceptible to environmental carcinogens.

4. Central lung cancer patients are generally treated with surgery, but early diagnosis of central lung cancer is difficult and usually incurable. 86% of patients will die within 5 years after diagnosis. If early diagnosis and timely treatment are possible, the 5-year survival rate can reach 50%. After treatment, patients need to review chest X-rays or CT scans every 3 months to monitor the efficacy and detect tumor recurrence or metastasis early.

The care of patients with central lung cancer should minimize exposure to dangerous environmental factors related to lung cancer in daily life. It should be noted that the disease requires long-term regular follow-up. If nausea, vomiting, abdominal distension and other discomfort occur during the use of chemotherapy drugs, the doctor should be notified in time. Most patients with central lung cancer need chemotherapy. The patient has a poor appetite and the diet should be light, easy to digest, and less fiber. Eat more foods rich in protein, iron and vitamins, and avoid spicy and irritating foods.
