“Food Feels Rough Going Down” ... The Esophagus’s Warning [Health Talk]

[Financial News] If the feeling that something is stuck in your throat or chest when you swallow persists, don’t dismiss it as simple indigestion. It could be a sign of esophageal cancer.
Esophageal cancer is a malignant tumor that develops in the mucous membrane of the esophagus, the passage through which food travels. The esophagus is a tubular organ about 25–30 cm long, extending from the throat through the chest to the stomach. It is divided into the cervical esophagus in the neck and the thoracic esophagus in the chest. The trachea and major blood vessels lie right alongside it.
In a healthy esophagus, the mucous membrane is smooth, the tiny blood vessels are arranged regularly, and the inner passage remains open. By contrast, advanced esophageal cancer appears on endoscopy as a mass and ulcers, with narrowing of the esophageal passage. Early esophageal cancer, however, can present only as subtle changes in the mucous membrane, making it difficult to detect with standard white-light endoscopy alone.

The stage of esophageal cancer is determined by assessing how deeply the tumor has invaded the esophageal wall, whether it has spread to nearby lymph nodes, and whether it has metastasized to other organs, such as the liver or lungs.

Diagnosis is made through endoscopy and biopsy, while computed tomography (CT) is used to check for invasion of nearby organs and spread to lymph nodes or distant sites. Positron emission tomography–CT (PET-CT) can help find distant metastases that were not visible on CT, and endoscopic ultrasound is used when needed to assess how deeply the tumor has invaded and examine nearby lymph nodes.

If there are lesions suspected of being metastases, magnetic resonance imaging (MRI) or a biopsy may also be performed.


Treatment varies depending on the cancer’s stage, the tumor’s location and the patient’s overall condition. In the case of esophageal squamous cell carcinoma, which is common in Korea, early-stage cancer that remains in the superficial layer of the mucous membrane and carries a low risk of lymph-node spread can be treated with endoscopic resection while preserving the esophagus. If the final pathology results after resection show that the cancer has invaded the muscularis mucosae or the submucosal layer, doctors decide whether to add surgery or chemoradiotherapy.
Locally advanced esophageal cancer that can be surgically removed is treated first with chemotherapy or chemoradiotherapy before surgery. If surgery is difficult, chemotherapy and radiation therapy are given simultaneously with the aim of curing the cancer. If it has metastasized to other organs, systemic treatment—including cytotoxic chemotherapy, immunotherapy and targeted therapy—is the main approach.
Supportive care to manage symptoms and nutritional status throughout treatment is also important. If swallowing food is difficult, the form of meals can be adjusted. When necessary, a stent can be placed in the esophagus, or a percutaneous endoscopic gastrostomy, which connects a tube directly to the stomach, can help with eating and nutritional support. Weight, food intake, pain, nausea and vomiting should be monitored regularly, and potential side effects of treatment should be anticipated and managed.
Wang Ho-young, a professor of gastroenterology at Soonchunhyang University Seoul Hospital, said, “It is as important to accurately assess how far the cancer has progressed as it is to detect the lesion,” adding, “Because early detection can make it possible to treat the cancer while preserving the esophagus through endoscopic resection, I recommend that anyone experiencing difficulty swallowing food not delay and undergo an endoscopic examination.”
