A blockage or dull pain behind the breastbone when swallowing dry food

Introduction Blockage or dull pain behind the sternum during swallowing dry food is one of the early and middle stages of esophageal cancer. Mainly for progressive dysphagia, early can only be discomfort or blockage when swallowing, post-sternal pain or post-sternal discomfort when swallowing food.

Cause

Causes of blockage or dull pain behind the sternum when swallowing dry food:

(1) Eating habits: Eat foods that are rough, hard, and overheated for a long time, or excessive intake of irritating substances such as pepper, garlic, vinegar, tobacco and alcohol. The incidence of drinkers is more than 50 times higher than that of non-drinkers, and the incidence of smokers and drinkers is 156 times higher than that of non-smokers and non-drinkers.

(2) Nitrosamines and precursors: foods preferred by residents in high-incidence areas such as sauerkraut, bean paste, dried potato, dried radish, cornmeal, etc., contain more nitrosamines and precursors, and the latter undergo stomach acid action in the stomach. Can be reduced to nitrosamines.

(3) Nutritional factors and trace elements: The high-incidence area of esophageal cancer is caused by the lack of protein, vitamins and essential fatty acids in the diet, which causes the mucosa of the esophagus to proliferate and metastasize and further cause cancer. In the high-incidence area of esophageal cancer, the content of various trace elements such as molybdenum, copper, cobalt, iron and zinc is reduced due to soil and water sources, especially the lack of molybdenum increases the nitrate content in the soil, which is beneficial to the synthesis of nitrosamines.

(4) Genetic factors and oncogenes: Esophageal cancer has a significant family aggregation phenomenon. According to the high incidence of esophageal cancer, it can reach 27%-61%.

Examination of the sternum behind the sternum or dull pain when swallowing dry food:

A series of symptoms caused by the tumor further increasing by more than 2/3 of the esophageal circumference, the degree of which is proportional to the degree of involvement of the esophageal circumference. In addition to the symptoms of the above-mentioned early symptoms, the symptoms of the sternum are heavier when swallowed. The most prominent clinical manifestations of esophageal cancer patients are often weight loss due to eating difficulties, mental factors, nutritional disorders and other reasons.

Differential diagnosis

Differential diagnosis of blockage or dull pain behind the sternum when swallowing dry food:

Thoracic pain: The cause is generally related to trauma. When people carry heavy objects, sharply twist or cause chest injury, etc., cause acute damage to the thoracic joint cartilage, or viral infection caused by chronic strain or cold, resulting in thoracic rib joint cartilage. Edema, thickening of the aseptic inflammatory response and onset. Or costal cartilage developmental malnutrition, chest and rib joint inflammation, myofascial inflammation. Its clinical manifestations are pain in the front chest, mostly soreness, and the onset is sharp or slow. It is light and heavy. It can be caused by coughing, deep breathing, upper limb activity, and sometimes upper extremity. Check 2-5 costal cartilage. If it is not treated in time, there will be a recurrent trend.
