According to the Tokyo Metropolitan Medical Association Public Health Committee data in 2019, gastric X-ray examination (barium), which is commonly used in Japan as well as colorectal cancer examination, has been established as an effective mass screening.  This examination has provided data that there are many false negatives. According to it, the sensitivity of X-ray examination (barium) is 70-80%, which means that 2-3 out of 10  subjects with cancer won’t be diagnosed as cancer. Surprisingly, only 0.7% to 2% of subjects who were diagnosed with gastric cancer by this method were finally diagnosed with gastric cancer in a detailed examination, that is, only 1 to 2 out of 100 subjects who were diagnosed with gastric cancer. That’s the low precision. On the other hand, according to a report by Niigata City, the sensitivity of endoscopy (gastrocamera) was 96.8%, and 3 out of 100  subjects with cancer examined were overlooked as normal. In contrast, X-ray examination (barium) reported a sensitivity of 81.1%, meaning that 19 out of 100 similarly tested cancer subjects were overlooked as normal. Subjects with cancer that were overlooked were determined not to have cancer in the test, so if the cancer is left as it is, there is a high possibility that these subjects will lead to death. As I showed last time, people over 50 have a dramatically higher chance of developing cancer, and half of them will eventually develop some type of cancer, so endoscopy (gastroscope) should be done at least once every two to three years. I think you should. However, the scary thing is that 36 million of the 100 million adult men and women in Japan do not even get a health checkup once a year. I feel like I can understand one of the reasons why the average life expectancy of the British royal family is over 90 and that the average life expectancy of the rich is high.
