Cancers of the Colon,
Rectum and Anus
Colorectal cancer (or bowel cancer) is
one of the most common types of cancer in both men and women. Approximately four fifths of
these cancers are found in the colon (large intestine), and one fifth in the rectum.
Prevention and early detection of colorectal cancer is important. Some of most common
symptoms include a change in bowel habit (eg. constipation, and bleeding), mucus
discharge, and discomfort or pain in the lower abdomen. The vast majority of colon and
rectum cancers are adenocarcinomas, around 10% of these are mucinous (protein contained in
mucus). The median age at diagnosis is 70, age adjusted incidence rates are slightly
higher in males compared to females. A substantial proportion of cases are in those with a
genetic predisposition to colorectal cancer. Diet may also have an influence on the
incidence of colorectal cancer, diatry fibre, retinoids, and calcium are thought to be
protective, while high intake of animal fats may increases risk. Colorectal cancer may
develop from benign polyps (a polyp is a tumour on a stem most commonly found on mucous
membranes). World-wide about 782,000 people are diagnosed with colorectal cancer each
year.

Prevention and early detection of colorectal cancer
is important, many patients do not show symptoms until the disease has reached an advanced
stage; screening may help detect changes before they become cancerous, or catch the cancer
at an early stage. Screening may by targeted at populations thought to have a higher risk
of developing colorectal cancer (for example those over age 50, particularly those with a
1st degree relative dignosed with colorectal cancer, or familial predispostion to
adenomatous polyposis).

"Virtual colonoscopy" (VC) is a new
technique that uses computed tomography and advanced imaging techniques to produce three
dimensional views of the colonic mucosa similar to those of a "real"
colonoscopy. As this non-invasive technique develops research is being undertaken to test
how sensitive it is in detecting polyps and early colon cancer.
