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
Early esophageal cancer typically causes no signs or symptoms.
When to see a doctor
Make an appointment with your doctor if you have any persistent signs and symptoms that worry you.
If you've been diagnosed with Barrett's esophagus, a precancerous condition that increases your risk of esophageal cancer caused by chronic acid reflux, ask your doctor what signs and symptoms to watch for that may signal that your condition is worsening.
Screening for esophageal cancer isn't done routinely because of a lack of an easily identifiable high-risk group and the possible risks associated with endoscopy. If you have Barrett's esophagus, discuss the pros and cons of screening with your doctor.
It's not clear what causes esophageal cancer.
Esophageal cancer occurs when cells in your esophagus develop errors (mutations) in their DNA. The errors make cells grow and divide out of control. The accumulating abnormal cells form a tumor in the esophagus that can grow to invade nearby structures and spread to other parts of the body.
Types of esophageal cancer
Esophageal cancer is classified according to the type of cells that are involved. The type of esophageal cancer you have helps determine your treatment options. Types of esophageal cancer include:
- Adenocarcinoma. Adenocarcinoma begins in the cells of mucus-secreting glands in the esophagus. Adenocarcinoma occurs most often in the lower portion of the esophagus. Adenocarcinoma is the most common form of esophageal cancer in the United States, and it affects primarily white men.
- Squamous cell carcinoma. The squamous cells are flat, thin cells that line the surface of the esophagus. Squamous cell carcinoma occurs most often in the middle of the esophagus. Squamous cell carcinoma is the most prevalent esophageal cancer worldwide.
- Other rare types. Rare forms of esophageal cancer include choriocarcinoma, lymphoma, melanoma, sarcoma and small cell cancer.
It's thought that chronic irritation of your esophagus may contribute to the DNA changes that cause esophageal cancer. Factors that cause irritation in the cells of your esophagus and increase your risk of esophageal cancer include:
- Drinking alcohol
- Having bile reflux
- Having difficulty swallowing because of an esophageal sphincter that won't relax (achalasia)
- Drinking very hot liquids
- Eating few fruits and vegetables
- Having gastroesophageal reflux disease (GERD)
- Being obese
- Having precancerous changes in the cells of the esophagus (Barrett's esophagus)
- Undergoing radiation treatment to the chest or upper abdomen
As esophageal cancer advances, it can cause complications, such as:
- Obstruction of the esophagus. Cancer may make it difficult or impossible for food and liquid to pass through your esophagus.
- Pain. Advanced esophageal cancer can cause pain.
- Bleeding in the esophagus. Esophageal cancer can cause bleeding. Though bleeding is usually gradual, it can be sudden and severe at times.
You can take steps to reduce your risk of esophageal cancer. For instance:
- Quit smoking. If you smoke, talk to your doctor about strategies for quitting. Medications and counseling are available to help you quit. If you don't use tobacco, don't start.
- Drink alcohol in moderation, if at all. If you drink, limit yourself to no more than one drink daily if you're a woman or two drinks daily if you're a man.
- Eat more fruits and vegetables. Add a variety of colorful fruits and vegetables to your diet.
- Maintain a healthy weight. If you are overweight or obese, talk to your doctor about strategies to help you lose weight. Aim for a slow and steady weight loss of 1 or 2 pounds a week.
