Gastrointestinal Cancer

Gastrointestinal cancer, also known as gastrointestinal tract cancer, is cancer that starts in the digestive system. The digestive system includes the esophagus, stomach, small intestine, large intestine, rectum, and anus. Gastrointestinal cancer includes cancers of the esophagus, stomach, small intestine, colon, rectum, anal canal, liver, gallbladder, and biliary tract. Gastrointestinal cancer is the second leading cause of cancer-related deaths in the United States. Common risk factors for gastrointestinal cancer include age, smoking, diet, and family history. Other risk factors may include chronic inflammation or infection, alcohol use, and certain inherited genetic syndromes. Early symptoms of gastrointestinal cancer vary depending on the type and location of the tumor. Common symptoms may include abdominal pain, nausea, vomiting, weight loss, blood in the stool, and changes in bowel habits. If you experience any of these symptoms, it is important to speak with your doctor. Diagnosis of gastrointestinal cancer usually involves imaging tests such as a CT scan, MRI, or endoscopy. If a cancer is confirmed, other tests may be used to determine the stage of the cancer.
