Lung cancer, throat prophet! Doctor’s Advice: 4 Physical Symptoms That Indicate Lung Cancer
There are about 3.58 million new cancer patients in China every year, of which about 700,000 are lung cancer patients, accounting for about 20% of the total number of cancer patients, a very high proportion, and the number of people who die from lung cancer every year is as high as 500,000. The morbidity and mortality of lung cancer have been at the top of the list for a long time.
The increasing frequency of cancer is not without reason.
First of all, more than 80% of lung cancers are considered to be caused by long-term smoking (smoking includes active smoking, passive smoking, which is second-hand smoke). Research data show that the probability of lung cancer in smokers is 10 to 20 times that of non-smokers about.
Secondly, environmental pollution is also an important reason for the high incidence of lung cancer! Such as air pollution, formaldehyde pollution, dust pollution, lampblack pollution and so on. These may induce lung diseases, leading to inflammation, tuberculosis, fibrosis and so on in the lungs.
We can change the above two points, and there is one point that cannot be changed-heredity, and genetic defects can also lead to an increased risk of lung cancer.
The reason why the mortality rate of lung cancer is high is that it is discovered too late fundamentally. Nearly 80% of the people are in the middle and late stage and have no chance of surgery. For patients who can detect lung cancer in time and take the most correct treatment in time, their five-year survival rate can even reach 80%! The five-year survival rate is also clinically known as clinical cure.
How to detect lung cancer early? Watch for these symptoms.
In the early stage of lung cancer, our bronchi and throat will give an early warning!
Cough: This is the most common symptom of lung cancer, manifested as an irritating dry cough. The most intuitive difference from ordinary cough is that it is difficult to recover, even if you take cough medicine, there will be no obvious improvement.
Chest tightness and shortness of breath: This is caused by the tumor compressing the lungs or bronchi. As the tumor grows, the chest tightness and shortness of breath will become more and more serious, and symptoms of dyspnea and chest pain will appear.
Decreased lung capacity: To a certain extent, lung capacity can be used to check the health of the lungs. You can try to see how long you can hold your breath. The normal time is more than 40 seconds. If it is less than 40 seconds, it indicates that there is a problem with lung health.
Facial abnormalities: Lung cancer can lead to a decline in lung function and affect the ability to produce oxygen. Long-term hypoxia can lead to dull facial color. With severe hypoxia, eyeballs may protrude.
