Early Detection of Colon Cancer - Virtual Colonography
Q: What is colorectal cancer?
A: Colorectal cancer is cancer that develops in the tissues of the colon, which is the longest part of the large intestine and in the rectum which is the last few inches. Most colorectal cancers are called "adenocarcinomas," which are cancers that begin in the cells that make and release mucus and other fluids.
Q: Who is most susceptible to developing colorectal cancer?
A: Colorectal cancer is far more likely to occur as we age. Over 90 percent of people with colorectal cancer are diagnosed after age 50. The average age at diagnosis is 72. (source: National Institute of Health)
Q: How serious is colorectal cancer?
A: Colorectal cancer the nation's second leading cause of cancer deaths and the fourth leading cause of death overall in both men and women. In 2008, it is estimated that approximately 158,000 cases of colorectal cancer will be diagnosed in the United States and that almost 50,000 people will die of the disease.

Q: Why should I have a colorectal cancer screening?
A: Colon screenings have been proven to reduce colon cancer deaths up to 60%.
Q: What are the symptoms of colorectal cancer?
A: Colorectal cancer symptoms are most commonly associated with changes in bowel habits, including:
* Onset of diarrhea or constipation
* Feeling that your bowel does not empty completely
* Blood (either bright red or very dark) in your stool
* Narrow stools
* Frequent gas pains or cramps, or feeling full or bloated more often
* Sudden weight loss not associated with diet or exercise
* Feeling very tired all the time
* Nausea or vomiting
It is important to note that other health problems can cause these same symptoms and that usually, these symptoms are not due to cancer. However, anyone experiencing these symptoms should consult a physician at once.
Q: What is the screening process for colorectal cancer?
A: While there are several screening options, a colonoscopy has been proven to be extremely effective. There are two types of colonoscopies, optical and virtual. In the optical or traditional, colonoscopy, the physician examines inside the rectum and the entire colon using a long, lighted tube called a colonoscope. In a virtual colonoscopy, a tube is inserted only a few inches inside the rectum.
Q: What are the other differences between a traditional and a virtual colonoscopy?
A: A virtual colonoscopy takes less time, is more comfortable (because the tube insertion is only a few inches instead of the entire colon), and requires no sedation, so you can resume your normal activities sooner. In research performed at Boston University, most patients reported that the virtual colonoscopy is more comfortable than a traditional colonoscopy
