Early diagnosis and treatment of esophageal cancer is not difficult. Doing some calculations and turning difficulties into starting points, esophageal cancer is a kind of esophageal cancer originated from the mucous epithelial tissue of 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 that it has not been diagnosed at an early stage. The main reasons are: lack of medical knowledge and psychological confusion. Many patients do not feel unwell, but due to economic or work reasons, they “put off minor illnesses, suffer from major illnesses, and carry serious illnesses to the hospital”. Some patients are unwilling to undergo timely review and adhere to the treatment after the surgery. In today’s highly developed medical science, not only the dilemma of “staying in the hospital once, a year’s work is in vain; once the ambulance rings, a group of pigs are raised in vain” should be changed, but also the concept of “nine out of ten cancers are buried, and the rest are not cancers” should be changed even more. We should realize that medical treatment is not only for ourselves, but also for family happiness and social harmony. Check the cause, heredity or mutation On the surface, the occurrence of esophageal cancer seems to be related to chronic inflammation or traumatic damage of esophageal mucosa caused by long-term consumption of nitrosamine-containing or moldy food, lack of microelements, bad eating habits, food irritation, such as long-term consumption of sauerkraut, drinking strong alcohol, smoking, eating rough and irritating food, eating too fast and too hot, etc. However, in reality, the occurrence of esophageal cancer is not only for oneself, but also for social harmony of family. However, in fact, the occurrence of esophageal cancer is determined by genetic defects and gene variations. Many patients have family history, especially male relatives. Upon research, it has been found that the occurrence of esophageal cancer is also a result of genetic variation. The elders may pass down some of the mutated genes (i.e., high susceptibility of the offspring), but this is not enough to cause cancer to develop. Once the offspring is exposed to long-term adverse stimuli, it can cause gene mutation. For example, some patients have multiple paternal grandparents with esophageal cancer, and the males in their families are particularly good drinkers, and the patients can drink alcohol almost like water. Scientists are now trying to find these susceptible people and actively guide and intervene in the occurrence of esophageal cancer. Taking Zenith Flat Tablets has been proven to be an effective intervention method. Remember the jingle, early detection of cancer signs The jingle about esophageal cancer symptoms is: one pharyngeal obstruction, two chest pain, three sense of foreign body, four swallowing, five heart pain, six throat dryness, and seven sternum boring and swelling ferocious. All patients with the above symptoms should seek for medical treatment in time. At present, the commonly used examination methods include gastroscopy, esophagography and chest CT. Esophageal cancer develops from atypical hyperplasia, which can be stained by iodine. The use of iodine staining can make early cancer and precancerous lesions easy to detect. Early lesions mainly show inconsistency with the surrounding tissues under the microscope, which can be specifically classified as cryptic, vesicular, plaque and papillary types. Especially with esophageal ultrasound endoscopy, it has high accuracy in estimating the tumor condition and understanding the relationship between tumor and surrounding tissues and organs. With the improvement of gastroscopy technology, early esophageal cancer can be treated without opening the chest, and neither general anesthesia nor hospitalization is needed, and the tumor can be resected and cured only under gastroscopy, which can be called simple and economical. The results of long-term follow-up and statistical analysis show that the depth of infiltration of esophageal cancer can better reflect the early and late stage of the disease than the length. Only invading the mucous membrane layer is considered as early stage cancer (carcinoma in situ), invading the outermost fibrous membrane of esophagus or having lymph node metastasis is considered as advanced stage cancer, and those in between are considered as invasive cancer. Therefore, the use of three-field sweeping and radiation to prevent and remove metastatic lymph nodes is emphasized in the treatment.
