"Why Do Lung Cancer Patients Experience Coughing and Wheezing?"
Lung Cancer Symptoms and Causes: Cough and Shortness of Breath
Symptoms such as cough and shortness of breath in lung cancer patients may arise due to atelectasis caused by tumor compression. Additionally, these symptoms can also be attributed to obstructive pneumonia resulting from the metastasis of cancer cells to the pleura or mediastinal lymph nodes.
Causes
- Atelectasis: When a lung cancer tumor grows large, it can compress the bronchi, preventing air from entering the lungs and leading to atelectasis. This, in turn, affects normal respiratory function, manifesting as the aforementioned symptoms.
- Obstructive Pneumonia: If lung cancer metastasizes to the pleura, it may cause a significant accumulation of pleural effusion. Alternatively, metastasis to mediastinal lymph nodes can disrupt normal ventilation and gas exchange, also resulting in the observed symptoms.
Treatment
For early-stage lung cancer patients, radical treatment through surgical resection of the tumor, such as a lung segmentectomy, is feasible. Post-surgery, radiotherapy and chemotherapy may be administered as adjuvant therapies to prevent recurrence. For patients with advanced or intermediate-stage lung cancer, radiotherapy and chemotherapy are utilized to inhibit cancer cell proliferation and prolong survival. Additionally, prescribed cough suppressants, such as Dextromethorphan Hydrobromide Tablets or Compound Pholcodine Oral Solution, can alleviate discomforting symptoms. It is recommended that patients promptly consult a physician, undergo relevant examinations under medical guidance, and actively cooperate with targeted treatments.
In daily life, maintaining a positive mindset, avoiding excessive stress and anxiety, and adhering to a healthy diet that includes fresh fruits, vegetables, and protein-rich foods are essential for overall well-being.
