In terms of treatment methods, the commonly used methods for treating lung cancer in Japan are nothing more than surgery, radiotherapy, chemotherapy drugs and new drugs. So the treatment is similar to that in China.
But why is the cure rate of lung cancer so high in Japan? More advanced drug research and development is on the one hand, and more detailed diagnosis and treatment is also on the other. More because Japan pays more attention to physical examination, screening early lung cancer through physical examination, and intervening treatment before lung cancer worsens, the cure rate is naturally high.
And China itself does not attach importance to physical examination, and most of them just go through the motions. The diseases that can be detected by general physical examination are actually in the middle and late stages.
Japan has a lot to learn in lung cancer screening. The following content comes from Intimate for your reference.
At present, CT is the best method to screen lung cancer, but the effect of ordinary X-ray examination is not ideal. Ordinary private medical institutions often don't have CT inspection equipment, and CT inspection in top three hospitals is always in line.
In addition, equipment alone is not enough. At present, many diseases are judged by human experience. Like the screening of lung cancer, most of them are diagnosed by observing the medical images taken.
Of course, the doctors in domestic top three hospitals are excellent, but objective conditions such as too many patients often lead to misdiagnosis or even missed diagnosis.
In Japan, the graded diagnosis and treatment system is first adopted to effectively allocate medical resources, so that doctors have sufficient time to fully observe and communicate with medical examination users. Secondly, the setting of physical examination items is more complete.
For example, the screening of lung cancer is not only as simple as shooting image data, but also can be diagnosed by other blood indicators. So what are the screening programs for lung cancer in Japan?
How to check lung cancer in Japan? Pulmonary function examination:
One of the most basic indexes of lung function is actually vital capacity. By inhaling and exhaling, we can judge the development of lung and the elasticity of lung muscles, so as to preliminarily judge the health of lung.
Detection of expectorant cells;
The detection of sputum cells is the most basic examination for screening lung cancer. Sputum is secretion produced by tracheal mucosa of upper respiratory tract such as trachea and lung. If these organs are infected by bacteria, there will be bacteria in the sputum.
In Japanese physical examination, sputum-expelling cells are generally sampled from three containers in advance, which contain sputum-expelling cell culture solution, and the sputum on the day of physical examination, the day before physical examination and the two days before physical examination are collected respectively. This is to increase the number of expectorant cells and ensure the accuracy of the test results.
Advanced tumor markers:
Tumor marker is a blood index test. Current research shows that there are different hormones or special factors in the blood of cancer patients from those of healthy people. This examination can be used as an auxiliary means to judge whether the medical examiner has cancer. For example, Pro-GRP is one of the tumor markers of lung cancer.
However, it should be noted that this examination is not a sufficient and necessary condition for judging lung cancer. Simply put, the lung cancer markers of lung cancer patients must be abnormal. The abnormal results of tumor markers in lung cancer may be caused by some inflammation or physiological activities.
Medical images: X-ray film, chest CT.
X-rays are what we often call chest films. In the physical examination of screening lung cancer in Japan, X-rays are usually taken from two angles. One is the front, the other is the side, and the situation of the lungs is comprehensively judged from two angles through images.
When shooting, Japanese nurses or doctors will teach users how to pose by hand to ensure the clarity and accuracy of the shot image, and it is also convenient for Japanese doctors to judge the user's lung condition.
However, X-ray film has a limitation, because our organs are all overlapping, and the influence data obtained from the examination will show that many organs overlap, and some small lesions are difficult to find through X-ray examination. If X-ray can detect very obvious lesions, lung cancer at this time is generally in the middle and late stages.
So how to solve this problem? Don't be afraid, the Japanese physical examination will have chest CT to judge. Chest CT examination is like cutting bread, cutting the human body into layers. Observe each layer of the lung from the perspective of overlooking, so that even relatively early lesions can be observed.
However, there is little difference between Japanese and domestic instruments, but the accuracy of CT examination in Japanese physical examination is higher, in other words, there are more "slices", so the more tissues observed, the greater the possibility of screening lung cancer.
The above are some screening items for lung cancer in Japan, which basically cover blood and body fluids to various medical images. It is suggested that people with a family history of cancer, or people with long-term smoking habits, or people with long-term bad air environment, such lung cancer screening should be conducted once a year. Third, early detection and early treatment.
