Colorectal Cancer
A Step By Step Guide To Understanding Colorectal Rectal Cancer
The Colon, Rectum & Anus - what is their role and why is it important to know
Knowledge of anatomy and physiology allows for easy understanding of most anorectal pathology. Likewise anatomy and physiology is important for managing certain clinical conditions involving the colon such as Colon & Rectal Cancer. A review of anatomy and physiology of the colon, rectum, and anus with clinical correlation is presented.
What is Colorectal Cancer?
Colorectal cancer is the second most common cancer in the United States, striking 140,000 people annually and causing 60,000 deaths. That’s a staggering figure when you consider the disease is potentially curable if diagnosed in the early stages.
Who is at risk of Colon & Rectal Cancer?
Colorectal cancer is the second most common cancer in the United States. The average person's lifetime risk of developing it is about one chance in 20. The risk is increased if there is a family history of colorectal polyps or cancer, and is still higher if there is a personal history of breast, uterine or ovarian cancer. Risk is also higher for people with a history of extensive inflammatory bowel disease, such as ulcerative or Crohn's colitis
Screening & Surveillance
Many polyps and cancers of the colon and rectum do not produce symptoms until they become fairly large. Screening involves one or more tests performed to identify whether a person with no symptoms has a disease or condition that may lead to colon or rectal cancer. The goal is to identify the potential for disease or the condition early when it is easier to prevent or cure. Surveillance involves testing people who have previously had colorectal cancer or are at increased risk. Because their chance of having cancer is higher, more extensive or more frequent tests are recommended.
Later in the brochure, the tests and risk groups are defined. Also, your physician can further explain the tests and their value to you.
