How long can lung cancer inchoate symptom live

summary

Lung cancer occurs in bronchial mucosa epithelium, also known as bronchial cancer. Incidence rate incidence rate of lung cancer has increased significantly in many countries in recent 50 years. The incidence rate of lung cancer ranks the first in male malignant tumors, and the incidence of female is also increasing rapidly, accounting for second or third of the common malignant tumors in women. Lung cancer has become a major disease endangering life and health. Long term smoking is an important pathogenic factor of lung cancer. How long can lung cancer early symptom live? Three years or five years?

How long can lung cancer inchoate symptom live

First, although great progress has been made in the treatment of lung cancer, such as the comprehensive treatment of surgery, radiotherapy and chemotherapy, and the advent of new anticancer drugs, the prognosis of lung cancer is still very poor. The 5-year survival rate of lung cancer patients receiving treatment is 14%, compared with 11% 30 years ago. The high mortality of lung cancer is mainly due to the lack of early diagnosis and effective treatment. Even in the early stage, most of the patients are systemic diseases at the time of initial diagnosis.

The second aspect: surgical indications: (1) patients with stage I, II and some stage IIIA non-small cell lung cancer, who have the possibility of radical resection and the general situation is tolerable; (2) patients with stage I small cell lung cancer, who have the possibility of radical resection; patients with stage II small cell lung cancer, who have the possibility of radical resection after chemotherapy; (3) The nature of solitary spherical lesions in the lung has not yet been determined. If lung cancer is highly suspected or the possibility of lung cancer can not be ruled out, surgical exploration should be actively carried out. During the operation, frozen sections should be made to determine the nature of the operation; (4) for solitary metastatic or recurrent lesions in the lung without metastasis of other organs, surgery should be actively carried out. For patients with obstructive pneumonia or atelectasis but without histological and cytological diagnosis and clinically diagnosed as lung cancer, surgical resection should also be considered.

The third aspect: when the central part of lung cancer is necrotic and liquefied to form cancerous cavity, the X-ray signs are easily confused with lung abscess. Patients with lung abscess often have a history of aspiration pneumonia. In the acute stage, there were obvious symptoms of infection, a large amount of sputum, purulent and smelly. On X-ray film, the cavity wall is thin and smooth, with fluid level. The lung tissue or pleura around the abscess often has inflammatory lesions. During bronchography, the contrast medium can enter the cavity and often accompanied by bronchiectasis.

matters needing attention

1. The diet should be light and nutritious. Do not eat fried hot and dry food, fat and sweet food, cold and wet food and spicy food. 2. Postoperative patients (the diet should be mainly nourishing qi and blood, such as almond syrup, lotus root, fresh cabbage, white radish, etc.) 3. Prohibition and control of smoking: the mechanism of lung cancer caused by smoking has been studied clearly. Epidemiological data and a large number of animal experiments have fully proved that smoking is the main factor of lung cancer. 4. The diet should be rich in nutrition, vitamin A and D, and eat more fresh vegetables and fruits. 5. In the aspect of spirit, we should keep the spirit happy and upward, and can't be depressed for some small things. 6.
