Esophageal cancer starts in the esophagus but it The Acid Reflux Strategy Review  can develop outside the esophageal wall and spread to other body parts such as bones, lungs, liver and brain through the lymphatic system.

While squamous cell carcinoma is related to alcohol and any kind of tobacco use, adenocarcinoma is more related to gastroesophageal reflux disease. The development of adenocarcinoma from Barrett's esophagus is considered relatively rare, however its number is increasing higher than any other esophageal cancers.

Acid reflux is known to be one of the esophageal cancer culprits. The esophageal lining is not designed to be exposed to the acidic fluid from the stomach so it will cause inflammation in the esophagus and create a burning sensation or chest pain, also known as heartburn. Frequent exposure to the gastric acid can damage the esophageal lining and turn the squamous cells into glandular cells that are commonly found in the intestines. This adaptation develops Barrett's esophagus which is more resistant to the acid, however people with Barrett's esophagus have a 30 to 125fold increased risk of developing esophageal cancer, according to Dr. Romero, a gastroenterologist from Mayo Clinic. Around 10 percent of patients with GERD develop Barrett's esophagus, and the only way to confirm whether a patient has it or not is by doing endoscopy and biopsy, although endoscopy can't 100% detect all BE cases. People with Barrett's esophagus normally seek help because of GERD symptoms such as acid reflux or heartburn. Barrett's esophagus itself creates no clear symptoms so if a GERD patient experienced no acid reflux symptoms, he/she will probably never be aware of the BE existence.

People with esophageal cancer will find difficulty in swallowing  whether liquid or solid foods  and suffer from pain during swallowing. Food may stick in the esophagus and when regurgitation happens undigested food can be vomited.
