What is Colorectal Cancer?

Rate This

The colon is a major part of the large intestine and its function is to help with the digestion of food. After the food has been broken down and had all its nutrients absorbed by the small intestine, the liquid that is left over is sent to the colon. The colon’s job is to dehydrate the liquid and turn it into solid matter (stool). The stool then goes into the rectum where it is stored until the person is ready to have a bowel movement and expel it through the anus.

What is Colorectal Cancer?

Colorectal cancer is cancer of the colon and rectum. Sometimes the cancer may only be present in just the colon or the rectum but it is referred to as colorectal cancer because it is caused by the same type of cell, called a polyp. A polyp usually starts off benign (non-cancerous) but then can develop into cancer. Most cases of cancer develop from these polyps.

Stages of Colon Cancer

If you are diagnosed with colorectal cancer, your specialist will want to surgically remove your tumor or tumors. Through surgery, he will then be able to determine what stage of cancer you have.

Initial Stage Cancer - this is when the cancer cells are just in the deepest layer of the colon or rectum and have not spread anywhere else.

Stage 1: The cancer has grown through the first few layers of the colon or rectum and is found in one to three lymph nodes.

Stage 2: The cancer has grown into the muscular layer of the colon or rectum and is found in four or more lymph nodes.

Stage 3: The cancer has grown through the entire colon or rectum but has not spread to other organs in the body.

Stage 4: This is the most severe kind of cancer, where the cancer has grown through the entire colon or rectum or both and has also spread to other organs in the body, such as the liver or lungs.

Colorectal Cancer Warning Signs

So, how do you know if you have cancer of the colon or rectum? Here are the warning signs:
Changes in your stool – they become thin and string like or have blood in them.
