Gastric Cancer Overview: Causes, Symptoms, and Therapeutic Approaches

Gastric cancer is a major contributor to cancer mortality worldwide, as reported by the WHO. It originates when abnormal cells in the stomach lining proliferate uncontrollably, leading to tumor formation. While the precise causes remain unclear, several risk factors have been identified, including infection with Helicobacter pylori, tobacco use, consumption of diets rich in processed, salty, or fatty foods, genetic factors, and occupational exposure to fumes from coal and wood industries. Additionally, exposure to asbestos in certain workplaces increases the risk.

Common symptoms encompass indigestion, bloating, nausea, and fatigue. Initial signs may include acidity and minor discomfort but should not be disregarded if persistent. As the disease progresses, one might observe blood in stool, jaundice, unintended weight loss, heartburn, and vomiting. Diagnostic procedures involve imaging scans, blood tests, endoscopy, and tissue biopsies to ascertain tumor presence and stage. Treatment may involve surgery, chemotherapy, or combined therapies to eliminate cancer and prevent further spread.
