Is it necessary to have an annual physical examination?

This is necessary. \x0d\ Physical examination is mainly divided into three categories: \x0d\ 1. Medical physical examination \x0d\ Physical examination for the purpose of disease diagnosis and treatment due to disease symptoms. \x0d\2。 Social physical examination \x0d\ refers to the physical examination for admission, employment, going abroad, joining the army or engaging in special industries, which is based on specific work or behavior. \x0d\3。 Physical examination \x0d\ Physical examination for healthy or sub-healthy people who are not sick, newly ill or about to get sick, or called "preventive health examination". \x0d\ Physical examination can understand the health status of the examinee, make clear whether there are any abnormal signs in the body, and thus find out the disease clues and health hidden dangers at an early stage. Some abnormal signs belong to physiological variation (different from pathological variation, normal people can also appear, not diseases), and regular review is enough; Some abnormal signs may be disease risk factors, which need to be intervened and corrected by health promotion means; Moreover, some signs are the basis of disease diagnosis and need further examination and diagnosis. \x0d\80% of malignant tumors are not found early \x0d\ With the increase of age, the probability of human suffering from certain diseases will increase exponentially. Some special industries have to bear the risk of "occupational diseases", and the pressure of life is increasing, which leads to the spread of many diseases to younger groups. Most of these diseases have no obvious symptoms in the early stage, but they often have serious consequences. For many diseases, early detection and timely treatment are the key to determine the prognosis. \x0d\ At present, the disease with the highest annual mortality rate in China is malignant tumor. According to the current medical technology, 80%-90% of malignant tumors can be cured if they can be found early, and most early cancers can be eradicated by surgery and survive for a long time. For example, the 5-year survival rate of early detection of primary esophageal cancer is 90%~95%, the 5-year survival rate of early gastric cancer is above 9 1%, the cure rate of early breast cancer is above 95%, the survival rate of early detection of cervical cancer can reach 90%, and the early intestinal cancer can be cured by 80%. \x0d\ Unfortunately, at present, almost 80% of malignant tumors are not found in the early stage. This is not because of our medical technology and medical level, but because some diseases have no symptoms in the early stage and are often easily overlooked. \x0d\ The national cancer registration database reports that about 60% of cancer deaths in China can be prevented and avoided (65.9% for men and 42.8% for women); About 30-40% in developed countries. Some of them can be avoided by preventing factors that induce cancer, such as smoking, drinking and infection. Many early hidden diseases can also be found through regular physical examination, and early intervention can be carried out to control the development of diseases.
