Stomach cancer develops in the inner lining of the stomach. This type of cancer usually grows at a slower rate than other forms, and relatively mild symptoms are easily overlooked in the early stages.
Mild symptoms can include an episode of acid reflux, and should be monitored carefully.
Indigestion is a general term that describes discomfort in the upper abdomen.
Although it can be a symptom of stomach cancer, indigestion in most cases does not indicate a serious condition and can be treated with over-the-counter medications.
It is not unusual for people to experience mild indigestion after eating a large meal, or eating too quickly.
However, anyone who has frequent indigestion with acid reflux should speak to a doctor.
According to the British National Institutes of Health (NIH), GERD occurs when the sphincter muscle weakens and allows stomach contents to return. The result is a burning sensation in the middle of the chest.
And when someone experiences heartburn regularly, it can become a condition called gastroesophageal reflux disease (GERD).
In addition to causing heartburn, GERD often also shows a feeling of regurgitation, which is the sensation of liquid substances moving from the stomach up through the throat.
Dr. Geoffrey Alexander, professor of medicine and chair of the Esophagus Clinic at the Mayo Clinic, said these symptoms frequently occur after eating.
Symptoms of advanced stomach cancer may include vomiting, stomach pain, weakness, frequent burping, jaundice, fluid buildup in the abdomen, and difficulty swallowing.
The NHS said there are many potential symptoms of stomach cancer, but it can be difficult to detect.
And she continued: “It can affect the digestive process, such as: heartburn or acid reflux, problems with swallowing, feeling sick, symptoms of indigestion such as excessive belching, and feeling full very quickly when eating.”
Other common symptoms of stomach cancer include blood in the bowel movements. When the stomach or lining bleeds, the fluid may collect with the rest of the body’s waste products. Stool can appear with blood almost black.
While there are other causes for both dark and bloody stools, a medical examination is required for any significant changes in bowel movements.
