What are the symptoms of advanced esophageal cancer

Esophageal cancer is a common disease that seriously affects people's lives and health. Therefore, everyone should do a good job in preventing esophageal cancer. What are the symptoms of late esophageal cancer? Let's learn about it together. I hope the following introduction can be helpful to everyone.

1. Dysphagia. Progressive dysphagia is the main symptom of most patients when they seek medical treatment, but it is a late manifestation of the disease. Because the esophageal wall is elastic and has the ability to expand, dysphagia only occurs when about 2/3 of the circumference of the esophagus is infiltrated by the tumor. Therefore, after the above early symptoms appear, the condition gradually worsens within a few months, from being unable to swallow solid food to being unable to swallow liquid food. If the tumor is accompanied by inflammation, edema, spasm, etc. of the esophageal wall, dysphagia may be aggravated. The location of the obstruction often corresponds to the location of the tumor on the hand.

2. Food reactions often occur when swallowing difficulties worsen. The reflux volume is not large and contains food and mucus, and may also contain blood and pus.

3. Other symptoms: When the tumor compresses the recurrent laryngeal nerve, it may cause hoarseness; when it invades the phrenic nerve, it may cause hiccups or phrenic nerve paralysis; when it compresses the trachea or bronchi, it may cause shortness of breath and dry cough; when it erodes the aorta, it may cause fatal bleeding. When there is esophageal-tracheal or esophageal-bronchial fistula or the tumor is located in the upper esophagus, swallowing liquids often produces cervical sympathetic nerve paralysis symptoms.
