Weight Gain
Linked to Recurring Prostate Cancer
The
weight of a man when diagnosed with prostate cancer, along with how
much weight he gains after the diagnosis can predict how aggressive the
cancer will be and also its chances of returning.
New research
from the
University of Texas M. D. Anderson Cancer Center, in Dallas, shows men
who gain weight rapidly between ages 25 and 40 are twice as likely to
have their prostate cancer return after surgery than men who gained
weight more slowly. Those who gained about three and a half pounds per
year were most at risk.
Researchers
also found a higher risk of recurrence in men who are age 40 and obese
when they're diagnosed with prostate cancer.
"They are more
likely to
experience biochemical failure, which is when their PSA level rises,
and their failure is likely to come sooner after surgery than in men
who did not gain weight rapidly, or who were not obese," says Sara S.
Strom, Ph.D., of the University of Texas M. D. Anderson Cancer Center.
Researchers
suggest the
aggressiveness of the cancer is linked to how much a man weighs when
he's diagnosed with the disease, as well as his history of weight gain.
Strom says
it's not clear
how excess weight contributes to the progression of prostate cancer,
but it may be linked to changes in different hormones and/or poor diet
and inadequate physical activity.
