Progressive Gastrointestinal Neuroendocrine Tumors

What Is Progressive GI NET?

Gastrointestinal (GI) neuroendocrine tumor(s) (NET) is a rare form of cancer that starts in different parts of the GI tract. The GI tract is a part of the body’s digestive system, and is made up of the stomach, small intestine, colon, and rectum. When the tumor has grown, spread, or gotten worse, this is called progressive GI NET.

Understanding Progression

Progression means that the tumor has become worse or spread from where it started in the GI tract. By the time most patients are diagnosed, their GI NET has progressed. At this point, if removing the tumor through surgery is no longer possible, your doctor will recommend another treatment.

Understanding Nonfunctional NET

You may hear your doctor describe your GI NET as “nonfunctional”. This means that your tumor does not release hormones that cause specific symptoms.
