Under the action of oncogenes, once liver cancer occurs, it grows very fast. If the tumor is less than 5 cm in diameter, liver cancer will be detected, which only shows that this person is so lucky!
One? This has a lot to do with the characteristics of liver cancer. As we all know, the liver is one of the few organs that can be regenerated in the human body, which stems from the vigorous metabolism and active growth ability of liver cells. However, once liver cells are transformed into cancer cells, this powerful reproductive ability will be inherited, and the growth rate of liver cancer is quite fast. The liver is one of the most important organs of the human body, and it undertakes the task of "chemical factory", where the whole body's blood, nutrients and metabolic waste will gather, and cancer cells are most likely to transfer to various parts of the body from here.
Two? Real early cancer is not easy to find. 1? It takes at least ten months or more from the earliest appearance of liver cancer to the establishment of subclinical liver cancer diagnosis. At this time, there is no solid tumor, and liver cancer is difficult to be found. 2? It takes about 9 months from the appearance of tumor masses in the liver that can be detected by B-ultrasound, CT and other equipment to the appearance of symptoms of liver cancer. During this period, the tumor is very small, and there are more opportunities for surgical resection. The five-year survival rate after early resection is relatively high. Unfortunately, because most people have no uncomfortable symptoms, liver cancer is still difficult to find. Even the annual physical examination is likely to miss this window perfectly. 3? It takes about 4 months from discomfort to jaundice, ascites or distant metastasis. At this time, the discovery and diagnosis of liver cancer is no longer difficult, but the development of liver cancer has entered the middle stage, and the treatment has been very difficult. 4? Advanced liver cancer. From severe symptoms to death, it takes about 2 months. The whole course of liver cancer takes at least two years, but most people get sick in the last six months and then are diagnosed.
Three? What's the point of physical examination? Liver cancer is a special case. Most other cancers do not develop as fast as liver cancer, and the degree of malignancy is so high, and the window period for early detection is long. The annual physical examination is still of positive significance. On the other hand, the cost of physical examination is also different. For example, the AFP index of early liver cancer may increase, and the cost of this test is 80. But if you still want to check lung cancer, stomach cancer, bowel cancer, prostate cancer and breast cancer ... there are at least a dozen indicators that can be checked, and the total cost may be as high as several thousand (these results are not 100% sensitive and accurate). All diseases should be checked once a year. In addition to health awareness, it should also be supported by economic strength.
The more money you spend on physical examination, the worse the "cost performance". Ordinary people can choose the right one according to their own economic situation, and it is not necessary to be perfect. I believe that Ng Man Tat does not lack the economic strength, but the health awareness. The annual physical examination may not be possible. If it really happens, I think it's really fate. May there be laughter from him in heaven.
