Understanding Cancer Tests
Cancer Diagnosis - Diagnostic Imaging
Imaging—X-rays, CT scans, MRIs—is a process that produces pictures of body structures and organs. It is used to detect tumors and other abnormalities, to determine the extent of disease, and to evaluate the effectiveness of treatment.
Cancer Diagnosis - Laboratory Tests
Lab tests are used in cancer diagnosis to look for tumor markers. These are substances either released by cancer cells into the blood or urine or substances created by the body in response to cancer cells.
Cancer Diagnosis - Tumor Biopsy
A biopsy is a procedure performed to remove tissue or cells from the body for examination under a microscope. Some biopsies can be performed in a doctor's office; others need to be done in a hospital setting.

Cancer Diagnosis - Endoscopic Examination
An endoscope is a small, flexible tube with a light and a lens on the end used to look into the esophagus, stomach, duodenum, colon, or rectum. It can also be used to take tissue from the body for testing or to take color photographs of the inside of the body.
