While both colon cancer and gastric cancer are forms of gastrointestinal malignancies, they are not the same. Colon cancer originates in the large intestine, specifically in the colon or rectum, and is often associated with factors like diet and genetics. In contrast, gastric cancer, also known as stomach cancer, develops in the stomach lining and can be influenced by factors like diet, smoking, and certain infections. These cancers have distinct symptoms, risk factors, diagnostic methods, and treatment approaches, making it important for healthcare professionals to differentiate between the two when diagnosing and addressing these conditions.
