Bigger Waist, Bigger Colon Cancer Risk
Obesity -- Especially Abdominal Obesity -- Increases Colon Cancer Risk
Sept. 7, 2007 - The bigger your waistline, the bigger your risk of colon
This finding, from an analysis of 30 long-term studies of colon cancer,
reinforces the link between obesity and colon cancer in men and, to a lesser
extent, in women. Obesity, the study shows, boosts the risk of rectal cancer in
men but not in women.
Perhaps most importantly, the study suggests that belly fat is more relevant
to colon cancer risk than fat in other places. For every 4 inches gained around
the waist, the risk of colon cancer goes up 33% in men and 16% in women.
"Abdominal obesity was more strongly related to increased colon cancer
risk than was overall obesity," report study researchers Susanna C.
Larsson, MSc, and Alicja Wolk, DMSc, of the Karolinska Institute
in Stockholm, Sweden.
It's not clear why obesity is more likely to cause colon and rectal cancer
in men than in women.
The findings appear in the September issue of the American Journal of
