Esophageal cancer is a malignant tumor that develops in the esophagus. When detected early, surgical treatment can achieve a cure rate exceeding 90%. However, once the cancer progresses to an advanced stage and metastasizes, even with comprehensive treatment, the patient's 5-year survival rate becomes extremely low.
Therefore, early detection of esophageal cancer is crucial! These prominent symptoms must not be ignored:
1. Sensation of food getting stuck during swallowing
Patients with esophageal cancer first experience a sensation of food getting stuck while swallowing. In the early stages, this sensation is not severe and typically occurs only when swallowing harder foods.Swallowing softer foods, semi-liquids, or liquids typically does not cause this sensation.
However, this symptom progressively worsens. If the disease advances rapidly, patients may experience this sensation even when swallowing soft or liquid foods, accompanied by difficulty swallowing. In advanced stages, even drinking water can cause significant obstruction and difficulty.
II. Slowed Food Passage
Early-stage esophageal cancer patients often exhibit mildly slowed food passage. For instance, when eating rice, steamed buns, bread, or similar foods, patients may feel a sensation of food stalling or moving slowly during swallowing.
In the early stages, drinking water may temporarily alleviate this symptom. However, the discomfort typically recurs within days and progressively worsens.
III. Retrosternal Discomfort Alongside the sensation of food getting stuck, patients may experience a series of discomforts behind the sternum. The most prominent symptoms include a foreign body sensation behind the sternum or pain and burning sensations after swallowing.
Following esophageal cancer development, the esophageal mucosa undergoes erosion and congestion, forming ulcers and masses. When swallowing food, contact with the tumor stimulates nerves, causing retrosternal pain and burning sensations.
IV. Throat Discomfort
Patients with esophageal cancer often experience pronounced discomfort in the throat. This primarily manifests as a distinct sensation of a foreign object in the throat, occurring frequently even when no food has been ingested.
Additionally, patients may feel extreme dryness and tightness in the throat. This sensation becomes particularly pronounced after swallowing dry, hard, or coarse foods.
In summary, patients with esophageal cancer typically exhibit four distinct symptoms. Some may also experience significant weight loss and a stabbing or burning pain below the sternum. If these symptoms arise, prompt medical attention is essential. Should esophageal cancer be the cause, early, scientifically standardized treatment is imperative.
