I remember a study done before that spending one dollar in disease prevention is equivalent to saving seven dollars in disease treatment, a ratio of one to seven, the exact article still needs to be found. This is like investing, investing in prevention and early detection and early treatment, the money saved compared to passive treatment is very substantial. Just as the famous “Yellow Emperor’s Classic of Internal Medicine” in China says: “The upper work treats the untreated disease, not the treated disease, this is also called”, that is to say: the best stage of disease treatment should be in the early stage of the disease or before the disease occurs. Zhang Lei of the Department of Pulmonary Oncology of Tianjin Cancer Hospital cited two living examples, two female patients who were both in their 60s, one of them visited the doctor immediately because of the symptom of blood in stool, and colon cancer was detected at an early stage and surgically removed. The tumor in the intestine was so serious that it could not be removed surgically. In the end, chemotherapy and molecular targeting drugs were used, which cost almost 300,000 to 400,000. Imagine, if you spend a very small amount of money every year to check the stool occult blood test, check the CEA, or even do a colonoscopy, you will not spend so much money, the point is to be able to detect the tumor early, cure the disease, and get your life back. Therefore, from the perspective of cost effectiveness, I think if individuals can think clearly about this issue and invest more money in preventive medical checkups for diseases, especially tumors, it is much better than passively waiting for symptoms to appear before going to the doctor. In terms of health investment, individuals have to be aware of this, think things through and calculate this account clearly, so that it is beneficial for both individuals and families. As we said before, even rich people can get tumors, and if the tumor is at an advanced stage, no amount of money can cure it completely. However, in real life, from my own study experience abroad, rich people in developed countries do live longer than ordinary people (specific data to be added). In addition to the superior living environment and good lifestyle, if there is any difference between rich people and ordinary people in caring for their health, I think they are more willing to invest some money in medical checkups, early detection and prevention of diseases, so that even if they suffer from malignant tumors, they can be cured by early surgery and save a lot of money for themselves. Of course, the most important thing is that the investment gains tremendous priceless time, or life as long as possible.
