Stage 0 Rectal Cancer, also called Rectal Carcinoma In Situ, diagnosis means that abnormal cells are found in the Mucosa, the innermost layer of you rectum wall, shown here in pink.  These abnormal cells may become invasive cancer and spread into nearby normal tissue.

What Tests Will I Need and Why?

A Rectosigmoidoscopy (a thin tube with a camera that is introduced through your anus to see the inside of your colon) is usually the first step to identify the tumor inside your colon and take samples for analysis.

Blood and Imaging tests are done to understand your general health, confirm your diagnosis and determine your cancer stage.

Tissue analysis is also typically done through a biopsy to identify the cancer cell type, which is critical to finding the best treatment option for you.

If your treatment team has not already performed tests to determine your cancer’s features, please ask your doctor when these tests will be performed.
