    In the past 20 to 30 years, the smoking situation in my country is very serious, and nearly 300 million people have smoking habits. Long-term smoking can cause bronchial mucosal epithelial cell proliferation, phosphorous epithelium, and induce squamous cell carcinoma or undifferentiated small cell carcinoma. In addition, cooking smoke, which contains many harmful and even carcinogenic substances, can also cause lung cancer.
