Recently, CA: The Journal of Cancer for Clinicians published the global cancer statistics, the cancer incidence rate is 184/100,000, among which, the incidence rate for men is lung cancer, prostate cancer, colorectal cancer, stomach cancer and liver cancer in order, and for women is breast cancer, colorectal cancer, cervical cancer, lung cancer and stomach cancer in order, it is estimated that there are 7,000 cases of lung cancer, 5,000 cases of breast cancer, 4,500 cases of colorectal cancer, 3,000 cases of liver cancer in Shanghai every year. It is very alarming that there are 7,000 cases of lung cancer, 5,000 cases of breast cancer, 4,500 cases of colon cancer, 3,000 cases of stomach cancer, and 2,000 cases of liver cancer in Shanghai every year. The purpose of medical examination is to detect tumors at an early stage, and the cure rate of early stage tumors is 90%. With mature treatment methods, patients can be spared from radiotherapy, quality of life is guaranteed, and the family and even family and friends are spared from laboring to maintain their normal rhythm of life. At the same time, a large amount of medical resources can be saved. Is physical examination a big deal? The importance of the physical examination, but also know what the physical examination. At present, many medical checkups are focused on cardiovascular diseases, and the examination of tumors is often rough. Clinically, we have encountered many advanced tumor symptoms after 3 or 4 months of physical examination, and the physical examination is just a formality and does not have the desired effect. We must understand that some tumor indicators only have about 50% positive rate, and early stage tumors are even lower, i.e. more than 50% of tumors cannot be detected by blood test only, so there must be targeted examination items. To put it simply, for gastrointestinal tumors, the simplest physical examination is to check fecal occult blood, preferably, gastroscopy once a year, colonoscopy once every five years, if there are polyps and family history of intestinal cancer, then once a year, hepatitis B virus infection, liver ultrasound and AFP examination once every six months, mammogram once a year for women between 40 and 60 years old, extended to once every two years after 60 years old, chest X-ray once a year, gynecological examination once a year, etc. Gynecological examination once a year, etc. Finally, I would like to remind you that it is best to go to a regular medical institution for medical checkups. Some institutions have beautiful hardware and thoughtful services, such as providing milk, coffee and snacks, as if they are of a very high standard, but essentially the qualifications of the medical personnel are unknown, the quality control of the medical and technical departments is very poor, and the quality of medical examinations cannot be guaranteed, so we should keep our eyes open.
