The parts of the colon are named for the way food passes through them

  • The first part is called the two ascending points. It starts in a pocket called the colon, where indigestible food enters the small intestine. Continue to the right side of the abdomen (abdomen).
  • The second part is called the transverse colon. Cross your body from right to left.
  • The third part is called a descending colon because it descends (descends) from the left side.
  • The fourth part is S-shaped, so it is called a sigmoid. The sigmoid colon is associated with the rectum, which connects to the anus.

The ascending and transverse part is collectively referred to as the proximal colon. Descending colon and sigmoid colon are called Distal colon

STAGES OF COLORECTAL CANCER:

There are FIVE(5) main stages of COLORECTAL Cancer, starting at ZERO and going up to four. They are often written with the Roman Numerals I, II, III, and IV. Generally, we can say the lower the number, the less cancer has spread.

STAGE I Colon Cancer

In stage I Colon Cancer means that the tumor has spread beyond the inner lining but remains within the colon and has not spread to lymph nodes. Lymph nodes are small organs that are part of the immune system and act as filters.

STAGE II Colon Cancer

Stage II colon cancer extends through the thick outer muscle layer of the colon but has not spread to the lymph nodes.

STAGE III Colon Cancer

Stage III colon cancer has spread outside the colon to one or more lymph nodes.

STAGE IV Colon Cancer

Stage IV colon cancer has spread to other parts of the body, such as the liver or lungs. Cancer may be in the lymph nodes
