The reason behind occurrence of esophageal cancer is not clear. It is said that the cancer of the esophagus is caused when esophagus itself develops errors in DNA. The errors formulate cells to cultivate and multiply which after a level becomes unmanageable. The accumulation of irregular cells forms a lump in the esophagus that can grow up to overrun nearby structures and multiply to other body parts.

The subsequent risk factors may have an effect on whether a person develops cancer of the esophagus. Some of these risk factors are beyond doctor’s control; at the same time some others factors can be managed by changing the lifestyle of the patient.

Age: the majority people who are diagnosed with esophageal cancer are approximately over 50 years old.

Sex: Men are at a higher risk (approximately three times) to build up esophageal cancer than women.

Tobacco and Alcohol Use: Squamous cell cancer of the esophagus is stoutly linked with tobacco and alcohol usage. Studies have given away to the fact that avoiding tobacco and alcohol decreases the possibility of developing esophageal cancer.

Barrett’s esophagus: This increases the risk of adenocarcinoma of the esophagus for the reason that the gland cells in Barrett’s esophagus can turn out to be more abnormal in due course of time.

Obesity: People who are obese or heavy are at a higher risk of getting adenocarcinoma of the esophagus. This is explained by the fact that people who are fat are more prone to having esophageal reflux.

Diet: Eating less fruits and vegetables and certain other minerals and vitamins have been linked with a high risk of esophageal cancer.

Workplace exposures: contact with chemical vapors in certain workplaces may lead to an augmented risk of esophageal cancer.

Symptoms of esophagus cancer include:

Difficulty swallowing: soreness may occur when swallowing if the cancer is large enough to chunk the esophagus.
Weight loss without trying: One will lose weight without even trying to do so.
Chest pain, pressure or burning: Heartburn often occurs.
Fatigue: This can either be food or blood. You may throw up blood that has seeped from the cancer into your esophagus or abdomen.
Coughing or hoarseness: The need to regularly clear your gullet, and experiencing a croaky voice.
Black, tarry stools: Bleeding from the esophagus can show up as black, tarry stools as abdomen acid turns black.
