Recently, the National Cancer Center released the latest cancer report, announcing the incidence and mortality of malignant tumors nationwide in 2016. Data from 487 cancer registries across the country in 2016 were used, covering a population of 380 million. Lung cancer is the most common cause of cancer death for both men and women, according to the report. Lung cancer is the most common cancer, and there are reasons for death. Understanding these reasons and understanding the relevant knowledge of lung cancer can help people stay away from lung cancer.

Why is lung cancer the most common cause of cancer death?

There are many types of cancer, and the incidence and mortality of lung cancer are at the forefront.

According to the World Health Organization, about 8 million people die of cancer each year, and 1.3 million people die of lung cancer span>, ranked No. 1. The mortality rate of lung cancer is very high. Although it progresses slowly in the early stage, once it enters the middle and late stages, it develops very rapidly.

So the 5-year survival rate of early-stage lung cancer can reach 90%, but the mid-stage lung cancer will decline At 20%, advanced lung cancer drops to 5%. Among the lung cancer patients diagnosed every year in my country, more than 75% of them are in the middle and late stages of development, so the mortality rate is high. In conclusion, lung cancer is the most common cause of cancer death.

What signals does the body send when lung cancer strikes?

No one is afraid of getting cancer, because in recent years, the incidence and mortality of cancer have been on the rise. It is very important to know early prevention. When lung cancer comes, there will be these few Symptoms, we need to know.

1, dry cough

Lung cancer can cause a cough, usually a dry, irritating cough. The presence of malignant tumors will change the secretion of bronchial mucus and make it more sensitive to external stimuli.

2. Blood in sputum

In addition to coughing, lung cancer patients also Symptoms of blood in the sputum appear. It is mainly caused by the invasion of blood vessels by cancer cells, so we should pay more attention.

3, hoarse voice

Lung cancer tumor continues to grow, and mediastinal lymph node metastasis increases, which will invade the recurrent laryngeal nerve and cause vocal cord paralysis, so the voice will become hoarse. About 7% to 20% of lung cancer patients have such symptoms.

4. Dyspnea

Some lung cancer patients still have dyspnea in the early stage. This is because the tumor can cause pleural effusion, compress the lung tissue, and affect lung function.

How to do lung cancer screening?

People at high risk of lung cancer should be screened for lung cancer regularly.

The National Comprehensive Cancer Network publishes clinical practice guidelines for various malignant tumors every year, including lung cancer. Lung cancer screening items mainly include: chest X-ray examination, CT examination, sputum cytology examination, bronchoscopy, CT-guided percutaneous lung biopsy, etc.

Guidelines recommend people aged 55 to 77, or with a smoking history of 20 years or more of people are screened for lung cancer every year. Lung cancer screening cannot be used as a substitute for smoking cessation. It is necessary to actively quit smoking. After all, smoking is a high risk factor for lung cancer.

How to prevent lung cancer?

1. Quit smoking

Quitting smoking is the most important way to prevent lung cancer, because smoking will increase lung cancer is a risk factor for lung cancer. People who smoke more than 20 cigarettes a day and smoke for more than 20 years have 20 times the incidence of lung cancer than non-smokers. To quit smoking in the right way, seek help from a smoking cessation clinic if necessary.

Message from the doctor

Lung cancer is the most common cancer In my country, the incidence and mortality of lung cancer are at the forefront. Lung cancer can be cured in the early stage, and the 5-year survival rate can reach more than 90%, but if it develops to the middle and late stage, the treatment effect will be greatly reduced, and the 5-year survival rate will drop directly to below 5%. To this end, it is necessary to understand the early symptoms of lung cancer, conduct regular lung cancer screening, detect it in time, and treat it in time, so as to improve the five-year survival rate and avoid the result of death.
