What is the esophagus cancer?

Cancer, which comes from the esophagus, is called oesophageal cancer. This type of cancer usually develops on the mucosal surface of the esophagus and attacks the tissues below this surface when it spreads. Esophageal cancer is the seventh main cause of cancer death on the seventh main cause in the world. The highest rate of this cancer occurs in parts of Russia, China and Iran. Although both of them come from the esophagus, they develop in different types of cells and due to different pathological processes. Esophageal spinocellular carcinoma is more common in people who smoke and drink alcohol strongly, while the esophageal adenocarcinoma is associated with gastroesophageal reflux disease. Time, exposure to these toxic, irritants causes inflammation of the esophagus. Finally, inflammation leads to cellular changes that can lead to cancer. The contributing factors that may increase the risk of esophageal cancer include obesity, nutritional deficiency and human papillomavirus infection.

Symptoms of esophagus cancer include problems with swallowing solids and liquids, swallowing pain, weight loss, hoarseness, persistent cough and respiratory problems. The presence of hoarseness, cough and respiratory symptoms sometimes suggest that cancer has proceeded too far to respond well to surgery. Swollen lymph nodes in the throat or under colonies may be a sign of metastases. When metastases occur, the most common targets are the lungs and liver.

The

treatment options for these cancer include chemotherapy, radiation therapy, laser therapy, photodynatherapy and surgery. In most cases, patients will undergo at least two types of treatment. For example, surgery to remove most tumors is often followed by chemotherapy to kill any remaining cancer cells. The use of multiple treatment reduces the risk of metastases and cancer.

esophageal carcinomas are often diagnosed late in the progression of the disease that contributes to the overall poor prognosis. Treatment is exhaustedTales and advanced diseases are often undernourished because of the inability to eat. The five -year survival rate in esophageal cancer is approximately 15 percent. This picture varies according to the stage in which people receive the treatment and type of treatment they receive. When surgical removal is combined with pre -science radiation therapy and chemotherapy after surgery, the five -year survival rate can increase to almost 50 percent.
