Picture of Colon Cancer What are the stages of colon cancer? When a colorectal cancer is diagnosed, additional tests are performed to determine the extent of the disease. This process is called staging.

Staging determines how advanced a colorectal cancer has become. The staging for colorectal cancer ranges from stage I, the least advanced cancer, to stage IV, the most advanced cancer.

Stage I colorectal cancers involve only the innermost layers of the colon or rectum. Stage II cancers exhibit greater growth and extension of tumor through the wall of the colon or rectum into adjacent structures.

Stage III colorectal cancers manifest spread of the cancer to local lymph nodes. Stage IV metastatic colorectal cancers have spread, or metastasized, to distant organs or lymph nodes far from the original tumor.

With each subsequent stage of colon cancer, the risk for recurrent cancer and death due to spread of the cancer metastasis rises.

As noted, earlier cancers have lower risks of recurrence and death. By the time an individual has stage IV colorectal cancer, the prognosis is poor. However, even in stage IV colorectal cancer depending on where the cancer has spread the opportunity for cure exists.

What are the treatments for colon cancer? Share Your Story Surgery is the most common initial medical treatment for colorectal cancer. During surgery, the tumor, a small margin of the surrounding healthy intestine, and adjacent lymph nodes are removed. The surgeon then reconnects the healthy sections of the bowel.

In patients with rectal cancer, the rectum sometimes is permanently removed if the cancer arises too low in the rectum. The surgeon then creates an opening colostomy on the abdominal wall through which solid waste from the colon is excreted.

Specially trained nurses enterostomal therapists can help patients adjust to colostomies, and most patients with colostomies return to a normal lifestyle. For early colon cancers, the recommended treatment is surgical removal.

For most people with early stage colon cancer stage I and most stage IIsurgery alone is the only treatment required. Chemotherapy may be offered to some people with stage II cancers who have factors suggesting that their tumor may be at higher risk of recurrence.

However, once a colon cancer has spread to local lymph nodes stage IIIthe risk of the cancer returning remains high even if all visible evidence of the cancer has been removed by the surgeon. This is due to an increased likelihood that tiny cancer cells may have escaped prior to surgery and are too small to detect at that time by blood tests, scans or even direct examination.

Their presence is deduced from higher risk of recurrence of the colon cancer at a later date relapse. Drugs used for chemotherapy enter the bloodstream and attack any colon cancer cells that were shed into the blood or lymphatic systems prior to the operation, attempting to kill them before they set up shop in other organs.

This strategy, called adjuvant chemotherapyhas been proven to lower the risk of cancer recurrence and is recommended for all patients with stage III colon cancer who are healthy enough to undergo it, as well as for some higher risk stage II patients whose tumor may have been found to have obstructed or perforated the bowel wall prior to surgery.

There are several different options for adjuvant chemotherapy for the treatment of colon cancer.

The treatments involve a combination of chemotherapy drugs given orally or into the veins. The treatments typically are given for a total of six months. It is important to meet with an oncologist who can explain adjuvant chemotherapy options as well as side effects to watch out for so that the right choice can be made for a patient as an individual.

Chemotherapy usually is given in cycles of treatment followed by recovery periods without treatment.

Gastrointestinal disorders include such conditions as constipation, irritable bowel syndrome, hemorrhoids, anal fissures, perianal abscesses, anal fistulas, perianal infections, diverticular diseases, colitis, colon polyps and cancer. This PDQ cancer information summary has current information about the causes and treatment of gastrointestinal complications, including constipation, impaction, bowel obstruction, diarrhea, and radiation enteritis. It is meant to inform and help patients, families, and caregivers. Even though a family history of colon cancer is an important risk factor, a majority (80%) of colon cancers occur sporadically in patients with no family history of colon cancer. Approximately 20% of cancers are associated with a family history of colon cancer.

Side effects of chemotherapy vary from person to person and also depend on the agents given. Modern chemotherapy agents are usually well tolerated, and side effects for most people are manageable.UNDERSTANDING COLORECTAL CANCER Anatomically, the colon, or large intestine, seems like a single organ, a unified piece of human plumbing.
