summary

My uncle suffers from lung cancer. He smokes heavily in his daily life, which leads to the occurrence of lung cancer. Recently, he went to the hospital for surgical treatment. The doctor also told us about why someone smokes without lung cancer. Now I will tell you about this problem.

Why does someone smoke without lung cancer

First of all: for smoking patients who do not have lung cancer is relatively lucky, cigarette smoke contains carcinogens. Long term smoking can induce bronchial epithelial cell proliferation, squamous cell carcinoma or undifferentiated small cell carcinoma.

Secondly, radioactive substances such as uranium and radium and their derivatives can induce the occurrence of lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.

Finally, chronic lung diseases such as tuberculosis, pneumoconiosis, silicosis, etc. can coexist with lung cancer. These cases incidence rate of cancer is higher than that of normal people. Besides, chronic bronchobronchial inflammation and lung fiber scar lesions can also develop into lung cancer.

matters needing attention

For patients with lung cancer, they should go to a regular cancer hospital for treatment as soon as possible. Lung cancer is also related to driving. Among men and women who drive for a long time, the number of lung cancer caused by long-term exposure to gasoline also accounts for a large proportion. It can be seen that the possibility of lung cancer caused by gasoline exposure can not be ignored.
