Causes of death from lung cancer with hematemesis

summary

My uncle got lung cancer last year, because he always coughs and coughs blood, so the doctor told my aunt to pay special attention to diet, only in this way can the disease not worsen. Eat more fruit and light some, next I will tell you about the cause of death of lung cancer hematemesis?

Causes of death from lung cancer with hematemesis

First, lung cancer occurs in bronchial mucosa epithelium, also known as bronchial lung cancer. Lung cancer generally refers to the cancer of lung parenchyma. The exact cause of lung cancer is still unknown. After many years of investigation and research, it is recognized that the following factors are closely related to the etiology of lung cancer. Smoking: long term smoking can cause hyperplasia of bronchial epithelial cells, phosphorous epithelia, squamous cell carcinoma or undifferentiated small cell carcinoma. It is recommended to reduce smoking or quit smoking, which is good for yourself and the people around you.

Second: it has been recognized that long-term exposure to radioactive substances such as uranium, radium and their derivatives, carcinogenic hydrocarbons, arsenic, chromium, nickel, copper, tin, iron, coal tar, asphalt, petroleum, asbestos, mustard gas and other substances can induce lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma; chronic lung diseases such as tuberculosis, silicosis, pneumoconiosis can coexist with lung cancer. The internal factors of human body, such as family heredity, decreased immune function, metabolic activity and endocrine dysfunction, may also play a certain role in the pathogenesis of lung cancer.   

Third: at present, smoking is considered to be the most important risk factor for lung cancer. There are more than 3000 chemical substances in tobacco, among which multi chain aromatic hydrocarbons (such as benzopyrene) and nitrosamines have strong carcinogenic activity. Multi stranded aromatic hydrocarbons and nitrosamines can lead to DNA damage in bronchial epithelial cells through a variety of mechanisms, which can activate oncogenes (such as Ras gene) and inactivate tumor suppressor genes (such as p53, FHIT gene), and then lead to cell transformation and finally canceration.

matters needing attention
