Why can't lung cancer brain metastasis be detected?

summary

The current lung cancer brain metastasis disease, for lung cancer I think you should have a certain understanding of it, we slowly found that such symptoms are more than some of the difference, this disease can always be a common disease, once suffering from that but great harm, so we should have a certain attention, otherwise the aggravation of the disease, it will take away our lives, this is our least Would like to see, then, lung cancer brain metastasis why not find out?? You know what? Today, let me share with you why brain metastasis of lung cancer can not be found?.

Why can't lung cancer brain metastasis be detected?

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

After daily nursing rounds, the cardiovascular, respiratory, digestive, urinary, motor and nervous systems were carefully examined and recorded. In addition to disinfection of ward and bedding, cleaning and disinfection of oral mucosa, skin and perineum should also be done; patients should be guided to rest, not to walk in other wards, reduce visits and avoid cross infection. Advise patients with lung cancer not to pick nose casually to prevent nasal bleeding; brush teeth with a soft toothbrush to prevent gingival bleeding.
