@amirk_hallaayoun: Symptoms of gastric cancer (or stomach cancer) can be nonspecific in the early stages, making it difficult to detect early. However, some of the most common symptoms include: 1. Abdominal pain: Discomfort or pain in the upper abdomen. 2. Unintentional weight loss: Weight loss for no apparent reason. 3. Early satiety: Feeling of fullness after eating small amounts of food. 4. Nausea and vomiting: These may occur, especially if the tumor blocks the passage of food. 5. Difficulty swallowing (dysphagia): If the tumor is near the esophagus. 6. Persistent heartburn or indigestion: Burning sensation in the stomach or reflux. 7. Loss of appetite: Decreased desire to eat. 8. Dark or bloody stools: These may indicate bleeding in the stomach. 9. Fatigue: Due to anemia from chronic bleeding. These symptoms may be caused by other less serious conditions, but if they persist, it is important to seek medical evaluation. Upper gastrointestinal endoscopy is the only proven tool for early detection of gastric cancer. This procedure allows direct visualization of the stomach lining and biopsies to be taken if suspicious areas are found. In countries with a high incidence of gastric cancer, such as Japan and South Korea, screening programs using endoscopy are carried out in at-risk populations. Other methods, such as computed tomography (CT) or tumor marker tests, are not effective for early detection, but may be useful in staging and monitoring the disease. Gastric cancer has a better prognosis when detected in early stages, so endoscopy is essential in patients with persistent symptoms or risk factors (such as Helicobacter pylori infection, family history, or tobacco and alcohol use). #cancer #gastriccancer #detection #screeningcancer #endoscopy #helicobacterpylori #prdrpedrogutierrezcontreras #endobraquiesofago #canceresofagogastrico #esofagobarret #mexico🇲🇽 #maroc🇲🇦
