Colorectal cancer is colon cancer (colon) and rectum (colon end). Colorectal cancer is also known as colon cancer. Given that most of these cancers come from bowel tissue gland (adenocarcinoma), this article will only refer to colon and rectal adenocarcinoma.

Colorectum Cancer Stage

Knowing the stage (stage) of cancer can help the doctor to plan the treatment. The following levels are used for colorectal cancer.
Stage 0
Early stage cancer. Cancer is still confined to the intestinal tract of the intestine. This stage is also known as in situ carcinoma or intramucosal carcinoma.

Stage 1
Cancer has penetrated the deepest layers of the intestine but has not reached the outer wall layer.

Stage 2
Cancer has spread to the outer wall of the colon or rectum, but does not involve the lymph nodes.
(The lymph nodes are small structures such as nuts that are part of the system body defense) or other body parts.

Stage 3
Cancer has spread to the nearby lymph nodes but has not spread to other parts of the body.

Stage 4
Cancer has spread to other parts of the body such as liver, lung or bone.
This stage does not depend on how deep the cancer penetrates the intestinal wall and whether the cancer has spread to the lymph nodes.
