Calculate the account and turn the difficult point into the starting point Esophageal cancer is a kind of mucosal epithelial tissue originating from the esophagus, accounting for 2% of all malignant tumors. With early treatment, the five-year survival rate of esophageal cancer can reach 70% to 80%, and the overall five-year survival rate of esophageal cancer in China has reached about 40%. The reason why it is difficult to improve the five-year survival rate is because of the lack of early diagnosis. The main reasons are: 1.Lack of medical knowledge. 2. Psychological confusion. Many patients do not feel unwell, but due to financial or work-related reasons, they “delay minor illnesses, suffer from major illnesses, and only carry serious illnesses to the hospital”. Some patients are unwilling to review and adhere to the treatment on time after the surgery. In today’s highly developed medical science, not only the dilemma of “one hospitalization, one year of work for nothing; one ambulance, one group of pigs for nothing” should be changed, but also the concept of “nine out of ten cancers are buried, and the remaining one is not cancer” should be changed. We should realize that medical treatment is not only for ourselves, but also for family happiness and social harmony. Investigate the cause, genetic or mutation On the surface, the occurrence of esophageal cancer seems to be related to long-term consumption of nitrosamines or moldy food, lack of trace elements, poor eating habits, chronic inflammation or traumatic damage of esophageal mucosa caused by food stimulation, such as long-term consumption of sauerkraut, strong alcohol, smoking, preferring rough and irritating food, eating too fast and too hot. However, in fact, the occurrence of esophageal cancer is determined by genetic defects and genetic variants. Many patients have family history, especially male relatives. After research, it has been found that the occurrence of esophageal cancer is also the result of genetic variation. The elders may inherit some mutated genes (i.e., high susceptibility of offspring), but this is not enough to cause cancer to occur. Genetic mutations can be caused by long-term adverse stimuli. For example, some patients have multiple paternal grandparents with esophageal cancer, and all the males in the family are particularly good drinkers, and the patients can almost drink alcohol as water. Scientists are currently trying to find these susceptible people and actively guide and intervene in the occurrence of esophageal cancer. Taking augmentin tablets has been proven to be an effective intervention method. Remember the jingle to detect the signs of cancer early The jingle about esophageal cancer symptoms is: one throat obstruction, two chest pain, three foreign body sensation, four swallowing stop, five heart soreness, six throat dryness, seven post-sternal stuffiness and swelling. Patients with the above symptoms should seek medical treatment in time. The commonly used examination methods are gastroscopy, esophagogram, chest CT, etc. Esophageal cancer is developed from atypical hyperplasia, which can be stained by iodine. The use of iodine staining method can make early cancer and precancerous lesions easy to detect. The early lesions mainly show inconsistency with surrounding tissues under the microscope, which can be specifically classified into occult, cicatricial, plaque and papillary types. Especially with esophageal ultrasound endoscopy, it is highly accurate for estimating tumor condition and understanding the relationship between tumor and surrounding tissues and organs. With the improvement of gastroscopy technology, early-stage esophageal cancer can be removed and cured without opening the chest, and without general anesthesia or hospitalization, which is easy and economical. Long-term follow-up results and statistical analysis show that the depth of esophageal cancer infiltration can better reflect the early and late stage of the disease than the length. Those invading only the mucosal layer are early stage cancer (carcinoma in situ), those invading the outermost fibrous membrane of esophagus or having lymph node metastasis are advanced stage cancer, and those in between are infiltrating cancer. Therefore, the use of three-field clearance and radiation to prevent and remove metastatic lymph nodes is regarded as the focus of treatment.
