What Is Gastrointestinal Cancer?

Gastrointestinal cancer can develop anywhere in your digestive tract, an approximately 25-foot-long pathway from your mouth to your anus that includes your:

After cellular DNA changes cause abnormal cells to grow and divide very rapidly, a tumor can form in any of these organs when abnormal cells bind.

Gastrointestinal Cancer Symptoms, Causes and Treatment


In many cases, symptoms of gastrointestinal cancer do not become noticeable until the tumor grows and reaches an advanced stage. The most common sign is abdominal pain, which is often easily attributed to a less serious condition, such as a stomach virus. Some people also experience early satiety, which is a feeling of fullness after eating only a small amount of food.

The early signs of gastrointestinal cancer can also vary based on the type and location of the tumor. Esophageal cancer often causes difficulty swallowing; gastric cancer may produce ulcer-like symptoms, such as loss of appetite, bloating and indigestion. Colorectal cancer — the most common type of gastrointestinal cancer — usually causes bowel changes and bloody stools.

If you have symptoms that concern you, don’t delay care. We encourage you to consult with a gastrointestinal oncologist at Garnet Health. The key to effective treatment for gastrointestinal cancer is an early, accurate diagnosis, which is readily available to you here in Orange or Sullivan County. 


While the precise causes of gastrointestinal cancer are unclear, researchers have identified several risk factors, including tobacco use, excessive alcohol consumption and an unhealthy diet. Certain underlying medical conditions may also play a role in its development, including:

Additionally, a small percentage of gastrointestinal cancers are believed to be inherited.


Gastrointestinal cancer treatment can vary based on the type, location and stage of the tumor. Surgery, often the primary treatment, involves removal of the tumor and a margin of surrounding healthy tissue. If necessary to restore digestive function, an anastomosis procedure may be performed to reconnect the remaining portions of the organs partially removed. If the location of a tumor would complicate its removal or if its removal would significantly affect digestive function, chemotherapy, radiation therapy or targeted therapy may be an alternative to surgery.
