Gastric Adenocarcinoma at 20x Magnification
Individuals with stomach cancer commonly do not experience any symptoms during the early stages of the disease. Then, even when signs do develop, they are often non-specific, which can make a proper diagnosis difficult. Some of the many symptoms associated with the disease are loss of appetite, pain or discomfort in the abdominal region, heartburn, indigestion, nausea, vomiting, bloating, fecal blood, unexplained weight loss, weakness, and fatigue. Many other forms of cancer as well as less serious disorders have similar symptoms, so extensive medical examination is generally necessary in order for a doctor to determine that a patient is suffering form stomach cancer.
