  Colon Cancer   (Site not responding. Last check: 2007-10-14)
The transverse colon is attached to the posterior abdominal wall by a mesentery, which is a double layer of connective tissue through which blood vessels travel on their way to supplying blood to the colon.
The descending colon is like the ascending colon in that it too is firmly fixed to the posterior abdominal wall, while the sigmoid colon and transverse colon hang on a mesentery within the abdomen.
Colon Cancer staging is based on 3 factors: The level of penetration of the tumor through the bowel wall, involvement of draining lymph nodes, and presence of metastasis to the liver or other organs or involvement of contiguous structures adjacent to the bowel.

It is retained in contact with the posterior wall of the abdomen by the peritoneum, which covers its anterior surface and sides, its posterior surface being connected by loose areolar tissue with the Iliacus, Quadratus lumborum, aponeurotic origin of Transversus abdominis, and with the front of the lower and lateral part of the right kidney.
