GI oncosurgeons use various tests to diagnose cancer in the gastrointestinal tract. Common tests include endoscopy, where a thin, flexible tube with a camera is inserted to view the inside of the digestive system. Biopsies are often performed during endoscopy to collect tissue samples for examination under a microscope. Imaging tests such as CT scans, MRI, and PET scans help visualize tumors and determine their spread. Blood tests can identify tumor markers that suggest cancer. Additionally, procedures like colonoscopy and sigmoidoscopy are used to examine specific parts of the GI tract. These tests together provide a comprehensive assessment, aiding in accurate diagnosis and effective treatment planning.
