Malignant lesions of the esophagus
Introduction
Introduction Esophageal malignant lesions are esophageal environmental pollution, chemical pollution (chemical toxins), ionizing radiation, free radical toxins, microorganisms (bacteria, fungi, viruses, etc.) and their metabolic toxins, genetic characteristics, endocrine imbalance, immune dysfunction, etc. The result of carcinogenic factors and carcinogenic factors leading to canceration of normal cells in the body is often manifested as: local masses formed by abnormal proliferation of local tissue cells.
Cause
Cause
The occurrence of esophageal cancer is related to chronic nitrosamine stimulation, inflammation and trauma, genetic factors, and trace element content in drinking water, food and vegetables.

Unrestricted, endless proliferation, the body's nutrients are consumed in large quantities; cancer cells release a variety of toxins, causing a series of symptoms; cancer cells can also be transferred to all parts of the body to grow and multiply, resulting in body weight loss, weakness , anemia, loss of appetite, fever, and severe organ damage. In contrast, there are benign tumors, benign tumors are easy to clean, generally do not metastasize, do not recur, only squeeze and block the organs, tissues, but cancer (malignant tumors) can also destroy the structure and function of tissues and organs. Caused by necrotic hemorrhage and infection, the patient eventually died due to organ failure.
Diagnosis
Differential diagnosis
Differential diagnosis of esophageal malignant lesions:
Esophageal sarcoma: The origin of smooth muscle, fibrous tissue and striated muscle tissue is more common, the tumor is often larger, and the clinical symptoms are similar to esophageal cancer. rarely seen. It occurs more frequently in the middle and lower part of the esophagus. The main symptom is difficulty swallowing. Tumors often have pedicled polypoid or nodular shape, and bulge from the side wall of the esophagus to the lumen, and the X-ray shows a large filling defect. The surface is uneven, the mucosa may have a little shallow erosion area, the lumen enlargement may widen the mediastinum, the upper and lower ends of the tumor are at an acute angle to the normal esophagus, and the sputum may flow from the tumor to the esophageal wall to show the edge of the tumor surface. Obstruction is not obvious.
Esophageal black tumor: rare. The tumor is polypoid, lobulated or nodular, and there may be ulcers on the surface. X-ray shows that the tumor bulge protrudes into the esophageal wall cavity to form a large filling defect, and the lumen of the lesion is dilated, similar to esophageal cancer, lesions. It can be multiple, with multiple nodular defects, and the obstruction is not obvious.
Esophageal cancer (shi dao ai): also known as esophageal cancer (shi guan ai), is a malignant tumor that occurs in the esophageal epithelial tissue, accounting for 2% of all malignant tumors. About 220,000 people die from esophageal cancer every year in the world. China is a high-risk area for esophageal cancer. The death of esophageal cancer is second only to that of gastric cancer. The age of onset is more than 40 years old. Men are more than women, but in recent years, There is a growing trend among people under the age of 40. The occurrence of esophageal cancer is related to chronic nitrosamine stimulation, inflammation and trauma, genetic factors, and trace element content in drinking water, food and vegetables.
