Esophageal Cancer
About Esophageal Cancer
Esophageal cancer is a disease in which malignant (cancer) cells form in the tissues of the esophagus, the muscular tube that connects the throat to the stomach. It can occur anywhere along the length of the esophagus and typically begins in the cells lining the inside of the esophagus.
Common Symptoms
- Difficulty swallowing (dysphagia)
- Weight loss without trying
- Chest pain, pressure, or burning
- Heartburn or indigestion
- Hoarseness
- Chronic cough
- Vomiting
- Bleeding in the esophagus
Diagnosis
Diagnosis commonly involves imaging tests like barium swallows, endoscopy to visually examine the esophagus, and biopsies to collect tissue samples for laboratory analysis. Additional tests, such as CT, PET, or MRI scans, may be performed to determine the extent of the cancer.
Causes
The exact causes of esophageal cancer are not fully understood, but certain risk factors are commonly identified. These may include chronic irritation of the esophagus, such as from gastroesophageal reflux disease (GERD), smoking, heavy alcohol use, and obesity.
Treatment Overview
Treatment for esophageal cancer often involves a combination of approaches tailored to the individual's specific situation, which may include surgery to remove the cancerous part of the esophagus, radiation therapy, and chemotherapy. Some individuals also explore complementary approaches, such as nutritional support or mind-body practices, in conjunction with conventional medical care to manage symptoms or improve quality of life. The choice of treatment depends on factors such as the cancer's stage, location, and the individual's overall health.
Prognosis & Outlook
The prognosis for esophageal cancer can vary significantly depending on several factors, including the stage of the cancer at diagnosis, the specific type of cancer, and the individual's overall health and response to treatment. Earlier detection may be associated with a more favorable outlook.
Types & Variants
Adenocarcinoma
This type begins in the cells of mucus-secreting glands in the esophagus. It most often occurs in the lower portion of the esophagus and is the most common type in the United States, often linked to GERD and Barrett's esophagus.
Squamous cell carcinoma
This type begins in the flat, thin cells (squamous cells) that line the surface of the esophagus. It most often occurs in the upper and middle portions of the esophagus and is strongly linked to smoking and alcohol use.
