In order to reduce the risk of breast cancer, you might want to hit
the gym, or simply walk a few more steps every day. Numerous studies
suggest that people who exercise are less likely to get breast cancer.
That's why the National Cancer Institute is conducting a study to
see the effect that exercise has on inactive women who are at risk
of getting the disease.

Based on recent evidence that exercise can affect a person's risk
of developing different types of cancer, Dr. Jennifer Eng-Wong,
a medical oncologist at NCI, recently began a study to find out
more. Eng-Wong is looking for women between the ages of 18 and
75 who do not exercise regularly and are at high risk for breast
cancer or have survived breast cancer to participate in the 12-week
Eng-Wong said the study is different from previous studies in
that it asks volunteers to perform the exercise on their own and
work it into their daily lives.
In the first phase of the study, participants are asked to wear
an electronic pedometer to measure the amount of walking they do
in a week. At the end of the first week, if the pedometer shows
that the participant's physical activity is less than approximately
30 minutes of exercise per day, she will most likely qualify for
the second phase of the study, in which women are instructed to
take at least 10,000 steps a week.
At the beginning and end of the study, doctors take routine fitness
measurements like weight and body fat percentage, and also measure
the women's hormone levels. Women who have higher levels of two
hormones in particular, estradiol and IGF-1, have been found to
be at a higher risk for breast cancer. If the results show that
exercising can lower those hormone levels, it could offer a clue
as to how to prevent breast cancer.
"I think the question in this study is can we get sedentary women
at increased risk for breast cancer to increase their physical
activity. That's really the primary goal. And then, following that,
we are trying to get a sense of the mechanism of how exercise might
decrease the risk for breast cancer," Eng-Wong said.
Other qualifications for the study may include: women who have
had breast cancer and are currently cancer-free; women who have
had an abnormal breast biopsy; or women who have a family history
of breast cancer. Study-related tests are provided at no cost.
