5. Heartburn
It is quite common for a person to experience heartburn every now and again. In fact, heartburn and indigestion are common symptoms that a person may experience from time to time. So much so that most people do not think much about it when it does occur.
However, when a person has stomach cancer they may develop heartburn that simply will not go away no matter what they do. Indigestion, heartburn and other common symptoms that the gut is not right can be early warning signs of stomach cancer. Most of the time, these symptoms are the result of something other than stomach cancer.
However, they are a warning symptom that something is definitely wrong in the digestive tract and for this reason, it is important to let your doctor know if you experience heartburn and indigestion often so that they can rule out stomach cancer and determine the underlying cause of your discomfort.
