Gastrointestinal Cancer: Diagnosis

and Treatment Gastrointestinal (GI) cancer is a term used to describe any cancer that affects the digestive system, from the mouth to the small intestine and anus. The causes of GI cancer vary and can include lifestyle choices, environment factors, and genetics. Diagnosis of GI cancer typically involves blood tests, endoscopy, imaging tests, and biopsy. Treatment for GI cancer may include surgery, chemotherapy, radiation, or a combination of therapies. The type and stage of GI cancer, as well as the age, gender, and health of the patient, play a major role in determining the best approach to treatment. Early diagnosis and treatment often leads to better outcomes.
