Daily heartburn and acid reflux are not necessarily the manifestation of early stage of stomach cancer, but are mostly considered to be caused by inflammation, and cannot be judged as early stage of stomach cancer simply based on the symptoms of heartburn and acid reflux. The more common cause of daily heartburn and acid reflux is gastroesophageal reflux disease, which usually appears about one hour after meal. In addition, chronic gastritis, gastric ulcer, dyspepsia and other diseases may also present daily symptoms of heartburn and acid reflux. However, it is true that some patients with gastric cancer may also have symptoms of heartburn and acid reflux. If patients experience heartburn and acid reflux every day, there is no need to be too alarmed and patients are advised to go to a more specialized local hospital for gastroscopy. If the patient is sure that it is inflammation, anti-inflammatory treatment is sufficient; if it is diagnosed as stomach cancer, the patient needs to choose the suitable treatment method according to the patient’s physical condition.
