Stomach cancer is characterised by a growth of malignant cells within the lining of the stomach. Likewise called gastric cancer, this type of cancer is hard to detect because most people generally do not show symptoms in the earlier stages.
While stomach cancer is fairly rare compared to other kinds of cancer, one of the most significant threats of this disease is the difficulty of diagnosing it.
As stomach cancer does not usually trigger any early signs and symptoms, it usually goes undiagnosed until after it has spread to other organs in the body. This makes it harder to treat.
Your stomach together with the esophagus is just one part of the upper section of your digestive system. Your stomach digests food and then moves the nutrients along to the rest of your digestive organs, specifically the small and large intestines.
Cancer starts when cells in the body begin to grow out of control. This can happen in almost any part of the body. Cancerous cells can then spread to other areas of the body.
Similarly, stomach cancer occurs when normally healthy cells within the upper digestive system become malignant and grow out of control, forming a tumour. Stomach cancer grows slowly and tends to develop over many years.
What are the early signs of stomach/gastric cancer? In truth, there are rarely any early indications as stomach cancers often tend to develop slowly over many years.
Before a true cancer develops, pre-cancerous changes often happen in the inner lining of the stomach. These early changes rarely trigger symptoms, so they usually go undetected. In countries like Malaysia where screening for stomach cancer is not routine, most stomach cancers aren't discovered until they reached an advanced stage.
When stomach cancer does cause signs and symptoms, they can include:
Most of these symptoms could be caused by other ailments apart from stomach cancer, such as a viral infection or an ulcer. However, if you have any of these issues, particularly if they do not go away or get worse, you should see a doctor so that the cause can be found and dealt with, if required.

The doctor might order a blood test to search for anemia (low red blood cell count), which could be caused by the cancer bleeding into the stomach. A test might also be done to look for blood in your feces, which could also be a sign of bleeding in the stomach.
If stomach cancer is suspected, you will likely be referred to a gastroenterologist.Diagnostic tests specifically look for suspected tumours and other abnormalities in the stomach and esophagus. These tests may include:
Your specific treatment strategy will depend on the origin and stage of the cancer. Age and overall health can also play a role.
