What is Esophageal cancer?

Esophageal cancer is not very common in the United States. The esophagus is a hollow muscular tube, starting in the throat and ending at the stomach, and is used to carry the food you swallow to your stomach to be digested. It is hard to detect esophageal cancer in its early stages. Even if you get symptoms, they may not cause you to be alarmed and seek help from your doctor. However, as the cancer grows, symptoms may include dysphagia, chest pain, weight loss and coughing up blood. Treatments include surgery, radiation, chemotherapy and laser therapy. Esophageal cancer patients also need nutritional support.

How do I know if I have esophageal cancer and what are the symptoms of esophageal cancer?

Early stages of esophageal cancer do not display any recognizable symptoms. As the malignant tumors grows larger, people may notice one or more of the following symptoms:

• Dysphagia: This is the most common symptom of esophageal cancer. It causes problems swallowing, with the feeling like the food is stuck in the throat or chest. At first it is often mild, and then gets worse over time. At last, patients can no longer eat and can only consume water.

• Chest pain or chest burning sensation: Chest pain with swallowing may occur if the tumor is large enough to block the esophagus. Some patients describe a feeling of pressure or burning in the chest.

• Hiccups: This happens because of digestive dysfunction of the esophagus.

• vomiting blood: When a tumor invades a blood vessel, vomiting blood occur. This may be the first symptom in some patients.

• Weight loss: This occurs because swallowing problems prevent patients from eating enough to maintain their weight. Other factors include loss of appetite and increase in metabolism from the cancer.

Infections or other health problems may also cause these symptoms. Only a doctor can tell for sure. A person with any of these symptoms should tell the doctor so that problems can be diagnosed and treated as early as possible.

Who is at risk for esophageal cancer?

Studies have found a number of factors that may affect the risk of esophageal cancer. These risk factors are outlined in the table below:

• Gastroesophageal reflux disease (GERD): In some people, acid can reflex from the stomach into the esophagus. This disease is called Gastroesophageal reflux disease (GERD). Clinicl data show that people with GERD have a 2~16 times risk of getting adenocarcinoma of the esophagus than normal.

• Barrett's esophagus: Barrett's esophagus means the condition the squamous cells that usually line the esophagus is replaced with glandular cells when reflux of stomach acid into the lower esophagus continues for a long time.

• Achalasia: This disease is that the muscle at the lower end of the esophagus does not relax properly.

As the result, food has trouble in passing into the stomach and tends to collect in the esophagus and the esophagus above this muscle becomes dilated. People with achalasia have a risk of esophageal cancer that is at least 15 times normal.

• Stomach bacteria: Epidemiological survey demonstrates patients treated to get rid of H. pylori get adenocarcinoma of the esophagus more often than expected.

• Injury to the esophagus: Chemical such as lye may cause a severe chemical burn in the esophagus. The scar tissue can make esophagus very narrow after the injury heals. People with these narrow have a high rate of the squamous cell type of esophageal cancer after several years.

• Workplace exposures: Clinical survey show exposure to chemical fumes such as solvents used for dry cleaning may lead to an increased risk of esophageal cancer.

• Tobacco and alcohol

• Diet: About 15% of esophageal cancer can be linked to a diet poor in fruits and vegetables.

• Obesity

• Gender: Men have a 3-fold higher rate of esophageal cancer than women.

• Age: Most cases occur in those 65 and older.
