When I was at school, I had a physical examination every year until I got cancer. I don't know what to check, what is the necessity of checking?

It's really irritating "I had a physical examination every year when I was at school, and I didn't find it until I got cancer. I don't know what to check. What is the necessity of inspection? " This phenomenon should arouse the deep thinking of relevant departments! -Especially in hospitals that undertake physical examinations in various places, what is the quality of the medical equipment you use when you examine people? What is the level, attitude and responsibility of all the staff responsible for physical examination? The physical examination equipment and the sense of responsibility of physical examination personnel in many hospitals are perfunctory. It is not so much the poor equipment as the wrong understanding and attitude of hospital leaders and medical examiners. There is a problem with the sense of responsibility of hospitals and staff, and of course there is a problem with the professional level of medical workers, which leads to many hospitals' physical examinations of employees in various units being a mere formality, which has no practical significance! ! ! How irritating! ! ! !
