China is a high incidence area of esophageal cancer for unknown reasons. Current research has found that most of the eight cancer-causing factors that cause esophageal cancer are related to eating and drinking. Su Zijian, Department of Surgical Oncology, Quanzhou First Hospital The number of people who get esophageal cancer is higher if they eat foods containing nitrosamines, such as pickled products like sauerkraut and salted fish, or often eat moldy instruments. Those who like to eat hard and coarse food, hot soup, hot porridge, hot tea or spicy food for a long time, or those who have bad habits such as long-term fast food and overeating, these bad practices can cause mechanical and physical stimulation and damage to esophageal mucosa, thus inducing the occurrence of cancer. The serious pollution of drinking water and the significant increase of nitrate and nitrite in water will also increase the chance of esophageal cancer for drinkers. In the early stage, esophageal cancer is limited to the surface layer of mucous membrane, showing cancerous erosion, superficial ulcers or small plaques, some of which are only the size of rice grains, causing slight discomfort when eating hard food, foreign body sensation or rubbing sensation behind the sternum, and in the middle and late stage, choking symptoms may appear. In severe cases, it is often accompanied by reflux, continuous spitting and mucous sputum. If esophageal cancer invades and causes peri-esophageal inflammation, mediastinitis or deep cancerous ulcers, it will cause chest and back pain. When tumor invades blood vessels and ruptures them, it can cause fatal vomiting of blood. Invasion of the recurrent laryngeal nerve can lead to vocal cord paralysis, hoarseness, and choking and coughing when eating. The most common diagnostic means for patients with esophageal cancer is upper gastrointestinal imaging or gastroscopy. Esophageal laparoscopy is convenient, safe, less painful and has a higher accuracy rate. Please pay attention to dietary hygiene and correct bad eating habits to prevent the occurrence of esophageal cancer.
