Stomach cancer, or gastric cancer, originates in the lining of the stomach and can develop into a malignant tumor. It is often diagnosed at an advanced stage due to the subtlety of early symptoms, which may include abdominal pain, indigestion, nausea, and unexplained weight loss. Risk factors for stomach cancer include chronic infection with Helicobacter pylori bacteria, smoking, a diet high in salty or smoked foods, and a family history of the disease. Diagnosis typically involves a combination of endoscopy, imaging studies, and biopsy to confirm the presence of cancer cells. Treatment options depend on the stage of cancer and may include surgical removal of the tumor, chemotherapy, radiation therapy, and targeted therapies. Early detection is crucial for improving outcomes, as the prognosis for stomach cancer is generally better when the disease is caught in its early stages. Regular screening and attention to symptoms are important for individuals at higher risk of developing stomach cancer.
