A Gastrointestinal Stomal Tumor, or GIST, is a fairly rare tumor of the digestive tract. Though there are other kinds of tumors that can originate in this part of the body, GISTs are different because they're created in different kinds of cells than other GI tumors. Though GIST can become life-threatening-- as you'll see in this program-- medical science has discovered new ways to alter the progression of this disease. Also in this program, we'll meet patients who are living with GIST including one man who had a fairly large GIST tumor, yet is approaching life actively and very optimistically.
