| Exercise boosts chances of breast cancer survival |
Washington Hoy

Women stricken with breast cancer can boost their chances of survival
by 50 percent with some exercise, according to a study published Wednesday.
"This is good news for women with breast cancer," said Doctor
Michelle Holmes, a Harvard Medical School assistant professor who
led the study published in the Journal of the Medical Association
(JAMA).
"Women with breast cancer have little to lose and much to gain
from exercise," Holmes said. The study was conducted among some
3,000 nurses diagnosed with different stages of breast cancer between
1984-1998 and who were monitored until June 2002.
The research showed that walking at an average pace for three to five
hours a week reduced the risk of death by 50 percent compared to more
sedentary women.
"The most logical explanation is that physical activity lowers
hormone levels, and the lower hormone levels reduce the chances of
a recurrence," Homes said.
"Women don't have to run marathons for the maximum benefit,"
she added.
Some 211,000 new cases of breast cancer are diagnosed each year in
the United States, and 40,000 die of the disease each year, the second
deadliest after lung cancer. |
