Screening Procedures

Stomach and Small Intestine

Blood Tests

During a blood test, a sample of your blood will be taken to determine the functionality of the organs in your body. This can help determine if there is a potential presence of cancer.

Imaging Tests

During an imaging test, your doctor searches for abnormalities that could point to the presence of cancer. These imaging tests may include a CT scan, PET scan, MRI, or X-ray swallow study.

Endoscopy

During an endoscopy, your doctor uses a small camera tube that enters through your mouth and goes down into your stomach to check for signs of cancer.

Large Intestine

Stool Tests

There are various types of stool tests, but all include collecting either a sample or whole stool for testing. The stool is tested for various conditions such as blood in the stool or altered DNA.

Colonoscopy

During a colonoscopy, your doctor inserts a small camera tube into your rectum to check your intestine for abnormalities. During this test, the doctor could also remove tissue.
