Abdominal cancer refers to a variety of cancers affecting digestive system organs, including the stomach, liver, large intestine, small intestine, pancreas, gallbladder, esophagus, and rectum. It occurs when damaged or old cells divide and multiply quickly, resulting in a malignant mass tumor.
According to The Ohio State University, more than 250,000 cases of gastrointestinal cancer, or abdominal cancer, are diagnosed annually in the United States, which accounts for approximately 20 percent of newly diagnosed cancers in the U.S.
