There are two main reasons for the increase in the incidence of lung cancer. One is the poor living environment, which leads to a large number of tiny particles in the inhaled oxygen. Over time, it may cause lung cancer.
The other is smoking. There are more than 300 million smokers in China, and there are about 300 million passive smokers. Both active and passive smoking will cause serious damage to the lungs.
Due to environmental pollution and a large number of smokers, the incidence of lung cancer is still high. In addition to the incidence rate, the mortality rate of lung cancer ranks first all the year round, which is largely because 80% of lung cancer patients in China are in the middle and late stages. Cancer cells have metastasized, so it is difficult to treat and the prognosis is poor.
Moreover, many lung cancer patients belong to small cell lung cancer, and the malignant transformation is rapid. Last year, Ceng Weiquan, a Hong Kong actor, died of small cell lung cancer, less than a year from diagnosis to death.
Because many people find that lung cancer is already in the advanced stage, so many patients think that lung cancer suddenly appears! Actually, it's not like this. The growth of any living thing in the world has a process, and so does cancer, which needs to go through early, middle, middle and late stages. This process can be long or short.
Many people find that lung cancer is advanced because the early symptoms of lung cancer are not obvious and are ignored. So it has been delayed until the lung cancer develops to the advanced stage.
Doctor's tip: When lung cancer grows, what are the facial manifestations? 1. Facial fever: that is, we often say low-grade fever, often between 37 degrees and 38 degrees.
2. Persistent cough: The most typical facial manifestation of lung cancer is long-term cough, which is characterized by irritating dry cough.
3. Facial emaciation: Cancer cells need to absorb nutrients from the body when they grow, so cancer patients will lose weight quickly in a short time.
The right face is red: the lungs correspond to our right face. Unilateral (right) facial redness indicates that lung function is changing.
5. Gloomy face: The appearance of lung cancer will affect the respiratory function, leading to the reduction of inhaled oxygen and exhaled carbon dioxide. Too many toxins in the body will lead to facial blackening and dullness.
