10 Facts about Gastrointestinal Cancer

Recognizing Symptoms of Bleeding in the Digestive System

Identifying signs of bleeding in the gastrointestinal (GI) tract can be crucial in detecting the presence of gastrointestinal cancer. If the bleeding originates from the stomach or esophagus, an individual may experience vomiting blood that has a black, gritty appearance resembling coffee grounds, especially if digestion has already begun. On the other hand, bleeding from other parts of the GI tract can lead to the presence of bloody stool. The freshness and color of the blood can provide insight into the severity of the bleeding; a bright red color indicates that the bleeding is more severe, while the presence of black stool suggests slower blood loss. Additionally, individuals who have been experiencing bleeding for an extended period may also experience a general feeling of unwellness.


Diagnosis

Identifying gastrointestinal cancer typically begins with a doctor’s examination and a thorough discussion of symptoms. In particular, the presence of blood in the stool or vomit will prompt further investigation. To visualize any potential tumors, a common procedure called endoscopy is often performed. During an endoscopy, a small fiber-optic camera is carefully guided through the digestive tract. In cases where problematic findings are observed, a tissue biopsy is usually performed. This involves collecting a sample of the abnormal tissue which is then sent to a laboratory for examination to determine if it is cancerous. Alternatively, if endoscopy is not feasible or sufficient, an ultrasound scan may be employed by the doctor.
