Lung cancer, throat prophet! Doctor's advice: 4 manifestations in the body, suggesting 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 cancer population. The incidence and mortality of lung cancer have long been at the top of the list.
The increasing frequency of cancer is not without cause.
First of all, more than 80% of lung cancers are believed to be caused by long-term smoking (smoking includes active smoking, passive smoking, or second-hand smoke). Research data shows 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 lung inflammation, tuberculosis, fibrosis, and more.
The above two points can be changed, and the other point cannot be changed-heredity, and genetic defects can also lead to an increased risk of lung cancer.
The reason for the high mortality rate of lung cancer is that it was discovered too late. Nearly 80% of people are in the middle and late stages and have no chance of surgery. For patients who can detect lung cancer in time and take the most correct treatment in time, the five-year survival rate can even reach 80%! The five-year survival rate is also called clinical cure.
How to spot lung cancer early? Watch for these symptoms.
When lung cancer is in its early stages, 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, and 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 bronchial tubes. As the tumor continues to grow, 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 self-checked for 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 takes less than 40 seconds, it indicates that there is a problem with lung health.
Facial abnormalities: Lung cancer will lead to decreased lung function and affect the ability to produce oxygen, while long-term hypoxia will lead to dull facial color, with severe hypoxia, the eyeball may protrude.
