About Gastrointestinal Cancer

The gastrointestinal tract is a 25-foot-long pathway of hollow organs that extends from the mouth to the anus. Gastrointestinal cancer affects the gastrointestinal tract and other organs that are part of the digestive system, which include the anus, biliary system, colon, esophagus, liver, pancreas, rectum, small intestine, and stomach. Abnormal cell growth along any part of the gastrointestinal tract or any of the associated digestive tract organs can lead to a tumor or cancer.

Types of Gastrointestinal Cancer

Symptoms of Gastrointestinal Cancer

Often symptoms are not present until the cancer has become more advanced. Symptoms of gastrointestinal cancer also depend on the type of cancer present. Patients with esophageal cancer may experience difficulty swallowing whereas those with stomach cancer may notice ulcer-like symptoms, such as indigestion, loss of appetite, bloating, or pain. Liver cancer and pancreatic cancer can also lead to abdominal pain, and colorectal cancer often causes unexplained weight loss, changes in bowel function, and bleeding.

Risk Factors for Gastrointestinal Cancer

Researchers have found several factors that can increase a person’s risk of colorectal cancer, but it’s not yet clear what exactly causes the cancer.

Common risk factors for gastrointestinal cancers include:

  • Older age, usually over the age of 50, though it can occur at any age
  • A history of colorectal polyps or colorectal cancer
  • A history of ulcerative colitis, Crohn’s disease, or irritable bowel disease
  • Obesity
  • Lack of physical activity of regular exercise
  • Poor diet
  • Diets high in animal protein, saturated fats, or calories
  • Diets low in fiber
  • Smoking
  • Alcohol consumption
