Early symptoms of lung squamous cell carcinoma?

summary

Squamous cell carcinoma of the lung, also known as squamous cell carcinoma of the lung, including spindle cell carcinoma, is the most common type, accounting for 40% - 51% of primary lung cancer. Squamous cell carcinoma of the lung is more common in elderly men and is closely related to smoking. Squamous cell carcinoma of the lung is more common in central type of lung cancer, and tends to grow in the thoracic cavity. Squamous cell carcinoma of the lung grows slowly, metastases late, has more chances of surgical resection, and has a higher 5-year survival rate. Squamous cell carcinoma of the lung is less sensitive to radiotherapy and chemotherapy than small cell undifferentiated carcinoma. Early symptoms of lung squamous cell carcinoma? Let's talk about it

Early symptoms of lung squamous cell carcinoma?

20% - 30% of the patients had the first symptom. There are two causes of fever caused by squamous cell carcinoma of the lung. One is inflammatory fever, which is mostly around 38 ℃ and rarely over 39 ℃. Antibiotic treatment may be effective, but it often occurs repeatedly due to poor drainage of secretion; The second is cancerous fever, which is mainly caused by the absorption of tumor necrosis tissue by the body. This kind of fever and anti-inflammatory drugs are ineffective, and hormone or indole drugs have certain curative effect.

Cough is the most common symptom, with cough as the first symptom accounting for 35% - 75%. Cough caused by lung squamous cell carcinoma may be related to changes in bronchial mucus secretion, obstructive pneumonia, pleural invasion, atelectasis and other chest complications. For patients with smoking or chronic bronchitis, such as the degree of cough aggravation, frequency conversion, cough nature change, such as high pitched metal tone, especially in the elderly, we should be highly alert to the possibility of cancer.

Sputum with blood or hemoptysis is also a common symptom of lung cancer, as the first symptom of about 30%. Due to the rich blood supply and brittle texture of tumor tissue, blood vessels rupture during severe cough, which may also be caused by local necrosis of tumor or vasculitis. Hemoptysis is characterized by intermittent or persistent, repeated small amount of blood in sputum, or a small amount of hemoptysis. Occasionally, it is difficult to control massive hemoptysis due to rupture of large blood vessels, formation of large cavities or tumor breaking into bronchi and pulmonary vessels.
