Introduction of lung cancer

    Lung cancer refers to a malignant tumor originating from a bronchial mucosal epithelium or an alveolar epithelium, which is also known as primary bronchial lung cancer, and is the first cancer of the national cancer morbidity, accounting for 19.6% of all cancers, about 7.05 million per year. Death is 569,000. 

    Among them, the morbidity and mortality of male lung cancer account for all malignant tumors, the incidence of women accounts for the second place, and the mortality is second, the prognosis is poor, and the overall 5 years of survival is 17.4%.

    Common types: non-small cell lung adenocarcinoma, non-small cell pulmonary squamous cell carcinoma, small cell lung cancer.

    Targeted treatment: Targeted drugs of non-small cell lung cancer include Yisisha, Trinka, Afatib, Krrytib, Nawu, etc;

Among them, Trinko and Nawu combabble can be used to treat non-small cell lung squamous cell carcinoma;

Small cell lung cancer has no targeted drugs, but is alternative to chemotherapy.

    Pathogenic factors: Long-term smoking is the most important reason for lung cancer. The probability of smoking is approximately 10 times that of non-smoking.

Other risk factors also include helium, second-hand smoke, asbestos, atmospheric pollution and genes.

    High-risk group: age 50-75 years old, smoking ≥ 20 packs / year.

    Early screening: once a year, a low-dose spiral CT screening, can reduce the mortality of lung cancer, and only high-risk populations.

    Early symptoms: irritating dry cough, blood wire, chest tightness, fever and air promotion.
