Gastric cancer, also known as stomach cancer, occurs when cells in the stomach grow uncontrollably. This type of cancer can develop in different parts of the stomach and may spread to nearby organs. Symptoms often include persistent stomach pain, difficulty swallowing, and unexplained weight loss. Early detection is crucial for better treatment outcomes. Risk factors for gastric cancer include a family history of the disease, certain bacterial infections like Helicobacter pylori, and lifestyle choices such as smoking and poor diet. Regular check-ups and awareness of symptoms can help in early diagnosis, improving the chances of successful treatment.
