The gastrointestinal system, also known as the digestive system, consists of the esophagus, stomach, liver, pancreas, gallbladder, small intestine, large intestine, and anal region. The organs of the digestive system work together in a specific order and harmony to digest food taken in through the mouth, absorb it, and transport it to the bloodstream, ultimately delivering nutrients to the cells.

Early diagnosis is crucial in gastrointestinal cancers. Endoscopic examination of the walls of hollow organs, such as the esophagus, stomach, and intestines, with the aid of a camera, and biopsy if necessary for diagnosis, is very important. After diagnosis, radiological imaging (X-ray, ultrasound, MRI, CT, PET) is highly beneficial in evaluating the relationships with neighboring organs and the spread to distant organs.

In early-stage disease, surgery may be sufficient, while in more advanced stages, the addition of radiotherapy and chemotherapy increases the success of treatment. In some cases, radiotherapy and chemotherapy may be used as the primary treatment.

Early diagnosis saves lives. Therefore, any new symptoms or signs that were not present before should be taken seriously, and you should share them with your doctor without delay.
