With
With the improvement of our living standard and medical condition, the average life expectancy has been gradually increased, and we all wish to live a long and healthy life for ourselves and our families, and to stay away from diseases, especially cancer, which is feared by all. However, due to
social pressure, heredity and some factors of environment, the incidence of malignant tumors in various age groups is getting higher and higher. According to statistics, there are 3.12 million new cancer cases and 2.7 million deaths due to cancer in China every year. According to the World Health Organization
According to the forecast of World Health Organization, the number of new cancer cases will reach 20 million and 12 million deaths due to cancer in 2020. At present, the main malignant tumors with high incidence in China are lung cancer, breast cancer, colorectal cancer, liver cancer, thyroid cancer, stomach cancer and lymphoma. Because the early symptoms of tumors are not obvious, they often cannot be diagnosed and treated early. Cao Wenlan, Department of Oncology, Xiyuan Hospital, Chinese Academy of Traditional Chinese Medicine, we are familiar with the examination and diagnosis methods of common tumors, including: general laboratory tests, such as blood, urine, stool routine and biochemical tests; immunological tests, such as alpha-fetoprotein AFP, carcinoembryonic antigen CEA and other tumor markers; imaging tests, such as X-ray, B ultrasound, CT, MRI, PET-CT, etc.; endoscopy, such as fiberoptic bronchoscopy, gastroscopy, gastroscopy, lymphoma, etc. endoscopy, such as fiberoptic bronchoscopy, gastroscopy, enteroscopy, colposcopy, etc.; tumor cytology examination, such as sputum exfoliative cell examination, esophageal lancet exfoliative cell examination, cervical scraping examination, etc. All of these examination methods can be used for tumor examination and diagnosis. Various examination methods complement each other’s strengths and weaknesses, and doctors often analyze them comprehensively according to various results and finally reach a conclusion. However, cancer cell examination, including exfoliative cell examination (such as finding cancer cells in sputum) and tumor tissue section examination, is the best examination method for qualitative diagnosis and correct pathological typing of tumor, and it is also very significant for guiding treatment, which is the most reliable and the gold standard for confirming the diagnosis at present. However
it is difficult to make a diagnosis at the early stage of cancer, which is difficult to determine through imaging. At present, many medical check-ups flaunt their high-end instruments and advanced testing technology, as if a single drop of blood can “check all diseases”. In fact, blood sampling
The examination is only one of the clinical diagnostic tools, and can only diagnose part of the disease. In particular, a patient should not be “sentenced to death” simply on the basis of one blood test report. Until there is a clear diagnosis of the disease, do not assume that because you see a certain blood test that is mildly elevated, you will not be able to diagnose the disease.
In particular, one should not simply give a death sentence to a patient based on a certain blood test report until a clear diagnosis of the disease is made. So, what are the methods of tumor screening in clinical practice, and what diseases can be diagnosed by “blood test”?
