Esophageal cancer
Symptoms of esophageal cancer spread
The most typical symptom of esophageal cancer, especially in its advanced stages, is difficulty swallowing. As esophageal cancer progresses, patients may further experience difficulty swallowing semi-liquid food, eventually leading to difficulty swallowing even water and saliva. Additionally, as the cancer develops, it might compress the trachea, resulting in symptoms like sticky sputum and difficulty in expectorating. Consequently, due to difficulties in eating, progressive severe weight loss and fatigue often occur. Furthermore, some patients may also experience chest or back pain, and in some cases, an esophageal-tracheal fistula might occur, leading to severe respiratory difficulties and intense choking. Moreover, after advanced esophageal cancer has spread, it may also cause jaundice, ascites, and can metastasize to other parts of the body, potentially resulting in various symptoms.
How to treat esophageal cancer metastasis?
The metastasis of esophageal cancer involves several aspects. The first aspect is the metastasis of lymph nodes, including those around the esophagus. If the number of metastatic lymph nodes is small and the tumor's location is suitable for surgical removal, then surgery can still be considered. The second issue involves cases where there is lymph node metastasis but with a higher number and wider spread, making surgical treatment unfeasible. In such cases, radical radiotherapy and chemotherapy can be considered to treat the esophageal cancer. Of course, there are also some new methods available now, such as immunotherapy, which can be considered along with others. Also, to improve symptoms of esophageal stricture, using an esophageal stent to control the difficulty of swallowing associated with esophageal cancer is also possible.
