Cancer that originates in the stomach. At first, the symptoms of stomach cancer may mimic those of peptic ulcer disease. These include vague indigestion, loss of appetite, and discomfort after eating. In more advanced cases, there may be abdominal pain, weight loss, difficulty swallowing, frequent vomiting, and abdominal swelling. Signs of internal bleeding can appear. These include anemia, vomiting with blood, and melena (blood in the stool). Melena makes the stool black, sticky, and strong-smelling.
An aggressive tumor originating from the stomach lining is termed malignant. While the precise cause remains uncertain, there is a correlation between HELICOBACTER PYLORI infection and an elevated risk. Additional likely factors encompass tobacco use, alcohol consumption, and dietary habits, particularly the consumption of substantial quantities of salted or pickled foods. Pernicious anemia, partial gastrectomy, and being of blood group A also appear to heighten the risk. Stomach cancer is a rarity among individuals below 40 years of age and is more prevalent in men, especially among the Japanese population. Indicators might commence with diminished appetite and weight loss, potentially overlapping with symptoms of peptic ulcers, including a burning sensation in the abdomen, nausea, and vomiting.
Typically, diagnosis involves the utilization of gastroscopy along with biopsy procedures or barium X-ray assessments. If the tumor is identified in its early stages, a partial gastectomy might be undertaken. However, if the condition is more advanced, the primary effective solution is gastrectomy, entailing the complete removal of the stomach. In instances where the tumor has disseminated extensively, radiotherapy and anticancer medications could potentially extend one’s lifespan.
