Gastrointestinal cancers

Abstract

Gastrointestinal cancer is any cancer that affects the digestive system, including the esophagus, stomach, pancreas, liver, small intestine, colon, rectum, and anus. The most common types of gastrointestinal cancer are colon cancer, rectal cancer, stomach cancer, and liver cancer. The causes of gastrointestinal cancer can vary depending on the type of cancer. In many cases, it is caused by a combination of genetic and environmental factors. Prevention of gastrointestinal cancer remains a priority. However, patients at increased risk should be screened for early detection and chemoprevention. The type of treatment depends on how long the person has had the disease or what stage the cancer is at.
