Esophageal Cancer

The esophagus is a tube connecting the throat to the stomach. The mucosa and submucosa make up the inner lining of the esophagus, which is where esophageal cancers typically develop. Esophageal cancer is a treatable disease, but it is rarely curable.

Signs and symptoms of esophageal cancer include:

Difficulty swallowing (dysphagia).
Weight loss without trying.
Chest pain, pressure or burning.
Worsening indigestion or heartburn.
Coughing or hoarseness.
Loss of appetite or feeling full.

Risk Factors:

Several factors can increase the risk of esophageal cancer, including:

1. Smoking and excessive alcohol consumption: These are significant risk factors.
2. Gastroesophageal reflux disease (GERD): Chronic GERD can lead to Barrett’s esophagus, a condition that increases cancer risk.
3. Obesity: Being overweight can increase the risk of adenocarcinoma.
4. Certain genetic conditions: For example, esophageal cancer can sometimes run in families.
5. Diagnosis: Diagnosis typically involves a combination of methods such as endoscopy (using a flexible tube to view the esophagus), biopsy (taking a tissue sample for testing), imaging tests like CT scans or PET scans, and sometimes endoscopic ultrasound to assess the depth of cancer spread.

Treatment:

Treatment depends on the stage of the cancer and other factors, including the patient’s overall health. Options may include:
1. Surgery: To remove part or all of the esophagus.
2. Radiation therapy: To kill cancer cells or shrink tumors.
3. Chemotherapy: Using drugs to kill or slow the growth of cancer cells.
4. Targeted therapy and immunotherapy: These approaches are more specific and may be used depending on the cancer’s characteristics.
