Why does esophageal cancer hurt in the late stage?

The most typical disease in the middle and late stages of esophageal cancer is dysphagia. Usually, when you start chewing solid food, you can't swallow them smoothly. After washing with soup or water, you can swallow them. Then you can't swallow semi-liquid food smoothly. It's difficult to swallow liquid food. The degree of dysphagia is closely related to the pathological type, and the shrinkage type and medullary type are more serious. Generally, Western medicine uses tranquilizers, and when one tranquilizer fails, it will be replaced by another. Traditional Chinese medicine will use some Chinese medicine to relieve pain or eliminate pain.

Esophageal cancer tissue necrosis, ulceration or invasion of large blood vessels can cause vomiting blood or black stools. If the tumor invades the aorta, it can cause massive bleeding and lead to death. When esophageal lesions cause incomplete or complete obstruction of the esophagus, secretions will not drain smoothly and accumulate in the narrow upper part of the esophagus, which will stimulate reverse peristalsis of the esophagus and cause vomiting. Chest pain or back pain is one of the common symptoms of advanced esophageal cancer. The pain is divided into dull pain, stabbing pain, burning pain, dull pain, and may also be accompanied by a feeling of heaviness. Chest pain is usually caused by inflammation around the esophagus, mediastinitis, and may even involve nearby organs or paravertebral nerve tissue. Ulcerative and medullary pain accompanied by ulcers is more common.
