Women over 30 who exercise more than an hour a week reduce risk of breast cancer: A study at University of Northern Colorado
- Reported, May 13, 2012
group of 4296 women were asked to recall their physical activity levels during
four key stages of life: 10 to 15 years old, 15 to 30 years old, 30 to 50 years
old, and 50 years old and older.
The odds of developing breast cancer did not appear to change in relation to
exercise levels between ages 10 and 30, but women above age 30 significantly cut
their chances of developing breast cancer if they were more active, the
The study was led by Lisa Sprod of University of Northern Colorado in Greeley
and presented at the American College of Sports Medicine's annual meeting in
"An average amount of exercise was defined as 60 minutes per week," Miss Sprod
said. "so anyone exercising less than 60 minutes was below average, above 60
minutes was above average, and anyone that considered themselves 'highly
competitive' chose that category."
Fewer women who classified themselves as "highly competitive" between the ages
of 30 and 50 developed breast cancer, compared to women who were less physically
Women over the age of 30 who exercise for more than an hour a week could reduce
their risk of getting breast cancer, according to a new medical study.
Likewise, fewer women who classified themselves as highly competitive at age 50
or older developed breast cancer when compared to women who exercised less than
60 minutes per week.
"Preliminarily," Sprod said, "the take home message is that accumulating greater
physical activity after the age of 30 may play a role in reducing the risk of
developing breast cancer."
