This is a cancer that is located in the colon (large intestine) and/or rectum. Colon Polyps are a
major cause of colon cancer. It is believed that certain
types of polyps (adenomatous) eventually turn into cancer if
not removed. Colon cancer may also occur without polyps in
certain diseases, such as ulcerative
colitis.
Familial polyposis syndromes (i.e., genetic diseases with multiple Colon Polyps)
Surgical removal of the cancer
Surgical removal of metastases
(tumor spread) to liver and lung may be considered.
Chemotherapy and/or radiation
treatment for more advanced colorectal
cancer.
The earlier colorectal cancer is
caught, the more likely it is to be cured. Early colorectal
cancer has a very high survival rate. Current screening
techniques include:
Hemoccult cards -- set of three cards check for blood in stool every year, plus flexible Sigmoidoscopy
(short scope placed in rectum) every three to five years.
- It is unclear whether high-fiber diets (bran, whole grains) prevent colorectal cancer. For high-risk individuals, a high-fiber diet is still recommended.
