Big Data on Chinese People’s Health and Medical Care The internationally renowned consulting firm Deloitte released the “Health Care Forecast Report 2020”, which has a very unpromising forecast on Chinese people’s health. China’s hypertensive population has 160-170 million people with high blood pressure there will be more than 100 million people with diabetes, 92.4 million people with diabetes, 70-200 million people with overweight or obesity, 160 million people with dyslipidemia, and about 120 million people with fatty liver. On average, one person suffers from cancer every 30 seconds, one person suffers from diabetes every 30 seconds, at least one person dies from cardiovascular disease every 30 seconds, one third of patients die from adverse drug reactions, and the misdiagnosis rate of common diseases is as high as about 27%, and the misdiagnosis rate of major diseases is as high as about 40%. Can there be a way out for the health of Chinese people? Early detection of cancer is the root of disease control If cancer can be detected early, its cure rate is still very high. However, the current situation of cancer prevention and treatment in China is that patients are not in early stage when they are diagnosed, and they are already in late stage when they pass the tumor marker test results, and hospitals are mainly treating patients in middle and late stage. The cancer treatment capacity in China is not low, and the equipment and diagnosis and treatment level of some large hospitals are close to those of developed countries, but the capacity for cancer prevention and control is very low. In 2011, the World Health Organization proposed a new ratio that 40% of cancer patients can be prevented from cancer, 40% can be cured through early detection, early diagnosis and early treatment, and 20% can survive with cancer. This 442 ratio fully illustrates the necessity and importance of early detection and diagnosis of cancer. If cancer is detected at an early stage, it can be treated as a chronic disease after surgery, and there is no problem to survive for several years or a decade. Even if the signs of cancer can be detected earlier, the occurrence and development of cancer can be completely avoided or delayed through early intervention, early prevention, regular medical checkups and other interventions. Currently, the World Health Organization defines cancer as a chronic disease that can be treated, controlled, or even cured. That is based on early detection, early treatment, and the fact that in the future, with the progress of medicine, cancer can be treated like a chronic disease. Who need ultra early tumor screening? 1.People with high risk of tumor, 45 years old or above who live in big cities with high work pressure; 2.People with family history of tumor or susceptible to hereditary diseases; 3.People with long-term exposure to harmful chemicals or radiation for occupational factors; 4.People with chronic inflammation or precancerous lesions; 5.People with long-term smoking, alcoholism or bad habits; 6.People with excessive intake of high fat and obesity. What does early tumor screening check? Tumor screening is an important way to detect cancer and precancerous lesions at an early stage. Common methods of tumor screening include: blood test index, B-ultrasound, X-ray, anorectal examination, gynecological examination, mammography and palladium, etc. Blood test. Blood test is an important means to check early cancer, mainly to detect whether the indicators of various tumor markers in blood are elevated, in order to detect and identify various malignant tumors. For example, alpha-fetoprotein AFP can detect primary hepatocellular carcinoma and germinal gland embryonic tumor. When carcinoembryonic antigen CEA is significantly elevated, it is commonly found in colon cancer, stomach cancer, lung cancer and bile duct cancer; it is also elevated in the presence of liver cancer, breast cancer, ovarian cancer and pancreatic cancer. Gynecological physical examination. Used to detect early cervical cancer, with a detection rate of about 60% to 70%. Ultrasound. Can clearly detect the presence of masses and lesions in most organs throughout the body. X-ray chest film. It can directly show whether there is lung tumor or not, and also can look for chest tumor through indirect changes such as emphysema, obstructive pneumonia and pleural fluid. Anorectal finger examination. It can roughly determine the presence and nature of lesions in the anus and rectum 7 cm to 10 cm from the anal verge. Gastroscopy and enteroscopy. Directly observe the color, vascular texture and glandular opening pattern of the stomach and intestinal mucosa with the naked eye to identify whether there are lesions, and further biopsy can be done to confirm the diagnosis of suspicious lesions. The tumor screening items introduced above are the most basic ones, and people who are suspected of having tumor diseases or doing physical examination for prevention can do these examinations. After abnormalities are found, some of them need further examination to confirm. For early and ultra early detection of tumors, more sensitive examination items such as CT, MRI and TTM (thermal tomography) must be used to detect more early cancer patients and pre-cancerous people among the many asymptomatic people. The medical expenses of cancer patients often bring a heavy burden to families. Therefore, regular tumor screening is an important tool for early detection of tumors to prevent their malignant changes. It is worth mentioning that the time chance for early stage cancer to be detected is usually only 1 to 2 years, so it is recommended that those who need it should receive regular screening at large hospitals that are well-equipped.
