Colorectal cancer is the third most common cancer death in
the United States. An estimated 106,700 people are diagnosed
with colon cancer and 42,000 with rectal cancer in the United
States each year. An estimated 55,000 Americans are expected to
die from both this year.
In almost all cases, however, this disease is entirely
treatable if caught early by colonoscopy.
Incidence rates for colorectal cancer have declined slightly
over the past 20 years. Research suggests that the decline may
be due to increased screening and removal of polyps, which are
growths that can progress to cancer.
In addition to providing regular screening for colon cancer
through conventional colonoscopies, Duke abdominal imagers have
pioneered a simpler, less invasive screening method called
"virtual colonoscopy," a method that uses a CT scanner to look
at the colon, rather than a scope.
