The 5-year survival rate of patients with esophageal cancer after operation is very low, about 30%, so early detection, early diagnosis and early treatment should be carried out for esophageal cancer.

Incentives: carcinogens; Genetic factors; Eating habits such as long-term smoking, drinking strong liquor, eating hot food and having excellent food; Precancerous lesions caused by gastroesophageal reflux disease and Barrett's esophagus; Lack of nutrition and trace elements.

Introduction of intestinal cancer: Intestinal cancer is a malignant tumor that occurs in the mucosa epithelium of large intestine. It can be divided into colon cancer and rectal cancer. When colorectal cancer was discovered, almost 80% was in the advanced stage, and its morbidity and mortality were second only to gastric cancer, esophageal cancer and primary liver cancer.

How long can you live: Generally speaking, if it is an early tumor, the five-year survival rate is over 90%. Rectal cancer is in the middle stage. Through surgical resection and postoperative radiotherapy and chemotherapy, the five-year survival rate can reach more than 50%. In the advanced stage of rectal cancer, the specific survival rate is affected by many factors, and there is no exact data.

Prevention: A high-fiber diet can effectively reduce the risk of fatal cancer by 40%, especially colon cancer and rectal cancer. Therefore, eating broccoli, mustard, cabbage and other vegetables, fruits, cereals and beans can prevent colon cancer.

The causes of colorectal cancer are high-fat and low-fiber diet, lack of some trace elements, bad living habits such as smoking and drinking, obesity, psychological factors and so on. The cure rate of chronic rectal inflammation is high; The influence of high protein and low fiber diet and carcinogens can slow down intestinal peristalsis and increase intestinal absorption of toxins; Heredity. There were no obvious symptoms in the early stage, and the main symptoms of right colon cancer in the later stage were abdominal pain, anemia and abdominal mass. The main symptoms of left colon cancer are bloody stool or mucus bloody stool, abdominal pain and abdominal mass.
