Digestive System: An Overview
Detailed information on how the digestive system works, including a full-color, labeled illustration of the digestive system
Colorectal Cancer: Introduction
Colorectal cancer is cancer that starts in either your colon or your rectum. These make up the lower part of your digestive tract. In most cases cancer does not start in both the colon and rectum. But both types of cancer have a lot in common. So they are often called colorectal cancer.
Colorectal Cancer: Statistics
Most people who have colorectal cancer are older than 50. Find out who is most likely to get cancer and why.
Colorectal Cancer: Risk Factors
Some risk factors are out of a person's control, such as his or her age or family history. However, some risk factors — like diet and exercise — are factors a person can control.
Colorectal Cancer: Symptoms
Symptoms include a change in bowel habits; bright red or very dark blood in the stool; stools that are thinner than usual; stools that appear slimy or that have a mucous film on them; persistent gas pains, bloating, fullness, and/or cramps; unexplained weight loss; constant tiredness; vomiting
Hereditary Colorectal Cancer Syndromes: Familial Adenomatous Polyposis (FAP)
FAP is a syndrome characterized by a large number of benign polyps in the colon and rectum. Without treatment, a person with FAP has a nearly 100% risk of colorectal cancer.
Other Colorectal Cancer Syndromes
Several rare syndromes raise the risk for colorectal cancer. These disorders include Turcot syndrome, Peutz-Jeghers syndrome, juvenile polyposis coli, and MYH-associated polyposis.
Colorectal Cancer: Screening
People who have any colorectal cancer risk factors should talk to their doctor or nurse about when they should start checking for colorectal cancer and what tests they should have done.
Carcinoid tumor is a rare type of tumor that grows slowly.
Colorectal Cancer: Prevention
All people are at risk of colorectal cancer to some degree. But some people have a higher risk than others. What can you do to help protect yourself against colorectal cancer? There's no sure way to prevent it. But you can make changes in your life that will help you control as many of the risks as you can. Here are some choices you can make that may help.
