How many stages does adenocarcinoma have?

The earliest stage small intestine cancers are called stage 0 (carcinoma in situ), and then range from stages I (1) through IV (4). As a rule, the lower the number, the less the cancer has spread. A higher number, such as stage IV, means cancer has spread more.

What indicates the stage of adenocarcinoma?

Stages 0–4 In this understanding of cancer, stage 0 indicates that there are abnormal cells, but they have not spread. A higher stage indicates a larger tumor or that the cancer has spread into the surrounding tissue or lymph nodes. Stages 1–3 indicate that the cancer has not yet spread to other parts of the body.
