A biopsy of the esophagus is not necessarily cancer. When the doctor finds lesions in the esophagus during endoscopy, such as esophageal polyposis or esophageal leukoplakia, esophageal erosions, or when cancer is suspected, he or she will take a biopsy of the esophageal mucosal tissue and send it to the pathology department for biopsy, but it does not necessarily mean that it is cancer. If the biopsy result suggests inflammatory changes in the esophagus or benign hyperplasia of the mucosa, it is mostly due to esophagitis, esophageal ulcers, esophageal polyps and other diseases, and not cancer. If the biopsy reveals tumor cells, it is important to consider an esophageal tumor, and the specific type should be determined based on immunohistochemistry and other tests. Don’t have too much psychological pressure after the biopsy of esophagus, wait patiently for the pathological results, the doctor will formulate the next treatment plan according to the examination results.
