Gastrointestinal cancer refers to cancers that develop in the digestive system, including the esophagus, stomach, liver, pancreas, colon, rectum, and anus. These types of cancer are some of the most common and deadly cancers worldwide. Research in gastrointestinal cancer focuses on understanding the causes, risk factors, prevention, and treatment of these cancers. This includes studying the role of genetic mutations, lifestyle factors, and environmental exposures in the development of gastrointestinal cancer. Researchers also explore new diagnostic tools, screening methods, and treatment options, such as surgery, chemotherapy, radiation therapy, targeted therapy, and immunotherapy. Overall, the goal of research in gastrointestinal cancer is to improve early detection, increase survival rates, and enhance the quality of life for patients with these types of cancer.
