What diseases can be complicated by esophageal cancer?

Esophageal cancer is a malignant tumor that mostly occurs in the cervical, thoracic, and abdominal segments of the esophagus. Due to the particularity of the location of the lesion, patients who have undergone surgery for esophageal cancer may also experience various complications. Complications of esophageal cancer are more common in patients with esophageal cancer that has developed to the late stage. The complications manifested by patients are also various, and the causes of these complications are also different.

1. Esophageal perforation: Late-stage esophageal cancer, especially ulcerative esophageal cancer, causes perforation due to local erosion and severe ulceration of the tumor. Different symptoms occur due to different perforation sites and adjacent organs. Perforation of the trachea causes esophageal tracheal fistula, which causes choking and coughing when eating, especially when eating liquid food. Perforation of the mediastinum can cause mediastinitis, chest tightness, chest pain, cough, fever, increased heart rate and increased white blood cell count, etc. Perforation of the lungs can cause lung abscesses, high fever, cough, purulent sputum, etc. Perforation of the aorta can cause esophageal aortic fistula, which can cause massive bleeding and lead to death.

2. Vomiting blood and bloody stool: caused by tumor rupture.

3. Caused by cancer metastasis: such as cancer cells invading the recurrent laryngeal nerve, causing vocal cord paralysis and hoarseness; tumor compression and invasion of the trachea and bronchi, causing shortness of breath and irritating dry cough; invasion of the phrenic nerve, causing diaphragmatic paralysis; invasion of the vagus nerve, accelerating the heart rate; invasion of the brachial plexus, causing arm soreness, pain, and abnormal sensation; compression of the superior vena cava, causing superior vena cava compression syndrome; metastasis of cancer to important organs such as the liver, lungs, and brain can cause complications such as jaundice, ascites, liver failure, dyspnea, and coma.

Experts remind: Lack of protein, vitamins and essential amino acids in daily diet can lead to hyperplasia and metaplasia of esophageal mucosa, and then cancer. In addition, studies have found that the occurrence of esophageal cancer may also be related to the lack of trace elements such as iron, molybdenum and zinc. Therefore, daily nutrition and health care and diet conditioning should be done well to prevent complications of esophageal cancer.

In short, the causes of esophageal cancer are multifaceted, and so are the complications of esophageal cancer. They are the result of the combined effects of multiple factors and their mutual promotion. We should try to reduce the avoidable pathogenic factors and reduce the occurrence of esophageal cancer.

The above is a brief introduction to "What diseases may be complicated by esophageal cancer?" For people who are related to the pathogenic factors of esophageal cancer, it is recommended to take preventive measures for esophageal cancer and receive specific treatment according to the doctor's instructions. I hope that patients can recover soon! If you have other questions about esophageal cancer, please consult our experts online or call for consultation.
