New Technology Helps Colon Cancer
Detection: Canadian doctors think they've found a way
to detect the earliest signs of colon cancer. Normal searches
for the signs of colon cancer involve a colonoscopy -- sending
a camera up a person's colon to look for polyps -- the first
signs of cancer. But using a special blue light, researchers
have found even the smallest potential tumors reflect a different
color: They turn an angry red -- literally a red flag. A pilot
test found the new technique improved diagnostic accuracy and
found more than 18 per cent more polyps than did standard colonoscopies.
Calcium Help Fight Colon Cancer?
WEDNESDAY, July 20 (HealthDayNews)
-- Calcium supplements may help prevent the development of
polyps that can lead to colorectal cancer, but there's no
evidence calcium actually prevents the malignancy itself,
Colon Surgery An Excellent Approach:
MONDAY, July 18 (HealthDay
) -- According to researchers, this approach to colorectal
surgery using the laparoscope could reduce post-surgery complications.
Compared to traditional (open) surgery, the Laparoscopic procedure
causes less inflammation and places less stress on the immune
system, according to a study in the July issue of Archives
Colonoscopy Versus Virtual Colonoscopy:
A study published in April 2004 in the Journal of the American
Medical Association (JAMA) compared results of standard
colonoscopy versus virtual colonoscopy in over 600 patients
at nine major medical centers. Virtual colonoscopy had much
lower rates of successfully finding polyps than standard colonoscopy.
Virtual colonoscopy detected polyps of at least 6 mm in 39%
of patients and polyps of at least 10 mm in 55% of patients.
By contrast, standard colonoscopy detected 99% of polyps of
at least 6 mm, and 100% of polyps of at least 10 mm. In addition,
accuracy rates varied widely among the different hospitals.
The authors advised that until more improvement in training
and technique is achieved, virtual colonoscopy "is not
yet ready for widespread clinical application."
|Obesity Increases the Risk
of Getting Colorectal Cancer in Women:The study
of 1,050 women and 1,250 men found that women with a body
mass index (BMI) of 40 or more (considered obese) were
5.2 times more likely to have significant colorectal neoplasia
than women with a BMI of 25 or less (healthy weight).

Colonoscopy Better then Sigmoidoscopy
For Women: WEDNESDAY, May 18 (HealthDay
News) -- Colonoscopy is by far the best test to catch colon
cancer early in women, a new study claims. Colonoscopy, in which
the entire colon is examined, finds more precancerous polyps
than does flexible sigmoidoscopy, which only reaches only the
lower quarter of the colon, explained study author Dr. Philip
Schoenfeld, an assistant professor of gastroenterology at the
University of Michigan Medical School, in Ann Arbor. His report
appears in the May
19 issue of the New England Journal of Medicine.
Discovery: New Colon Cancer
Marker Found: Levels of molecule may predict severity
of disease and survival, researchers say. THURSDAY, Jan. 20
-- Harvard researchers have found a new marker that may signal
more invasive and lethal forms of colon cancer. These findings
could eventually lead to more targeted treatments and new ways
to screen for more aggressive disease, report the researchers.
