Cancer of the esophagus originates in the esophageal epithelium, of which it is an anarchic and infiltrating proliferation capable of propagating directly and through the lymphatic and blood channels.
The use of computed tomography largely eliminates the invasive methods of research in deciding the issue of tumor penetration beyond the limits of the esophagus. Computed tomography is used in the diagnosis of metastatic lesions of the liver and lymph nodes in the abdominal cavity.
Ultrasound Test examination:
Ultrasound examination is performed to detect liver metastatic lesions, detect enlarged lymph nodes in regional areas below the diaphragm and accessible areas of the mediastinum, retroperitoneal tissue, assess intra-stenotic tumor spread (when it is possible to carry out an esophageal esophageal transducer for the esophageal narrowing zone).Ultrasound examination of the neck, supraclavicular zones helps to identify metastatic lymph nodes.
X-ray of the upper gastrointestinal:
X-ray of the upper gastrointestinal (GI) tract: X-ray of the upper gastrointestinal tract or upper GI uses a form of real-time X-rays called fluoroscopy and barium contrast material to produce images of the esophagus, stomach, and small intestine. The patient drinks a contrast material that lines the esophagus and stomach, and x-rays are taken. This procedure is also called the upper GI series. The upper GI tract examination that focuses on the esophagus is called a barium swallow or esophagogram examination.
Radiographically, the most common symptoms of esophageal cancer are:
- The absence of the esophagus wall at the site of the tumor,
- Violation of the relief of the mucous membrane of the esophageal wall,
- Filling defect
- Narrowing of the lumen or infiltration of the organ wall.
Magnetic Resonance Imaging(MRI):
MRI can be used to see abnormal areas in the brain and spinal cord that may be due to the spread of cancer. And to show the details better, you can inject gadolinium (contrast material) into a vein before doing the study.
Echography to Endoscopy:
This imaging study is beneficial in determining the size of esophageal cancer and whether it has grown to nearby areas. It can also help show if adjacent lymph nodes may be affected by cancer.
Thus, the integrated use of X-ray, esophagoscopy, data from the morphological study of the material in most cases allows to correctly recognize the disease. In some cases, it is necessary to differentiate esophageal cancer with diseases such as cardiospasm, scarring structures of the esophagus, diverticula, benign tumors and ulcers of the esophagus.
Can esophageal cancer be prevented?
As with any disease, it is not possible to prevent esophageal cancer but to help the risks of suffering from it are significantly lower. How? Avoiding the following risk factors:
- Avoid the consumption of tobacco and alcoholic beverages.
- You must consume healthy foods and maintain a healthy weight.
- Reflux treatment can help prevent Barrett's esophagus (a condition in which the lining of the esophagus is damaged by gastric acid) and cancer of the esophagus.
- Those who suffer from Tilosis (a hereditary disease that causes excessive growth of the upper layer of the skin of the palms of the hands and soles of the feet) are more likely to develop esophageal cancer.
