Breast Cancer Prevention through Lifestyle

(Ivanhoe Newswire) -- A new study confirms what doctors and dieticians
have long said -- exercise and a healthy weight can significantly
improve your life and even reduce the early onset of cancer. In the
study, physicians from the University of Washington in Seattle report
cancer can be prevented in women with genes that put them at the
greatest risk.

Women who carry the genes BRCA1 or BRCA2 have a lifetime risk of
breast cancer of more than 80 percent. They also have an increased
risk for ovarian cancer. The new study findings indicate even among
this group of women, exercise and a healthy weight as an adolescent
led to delayed onset of cancer.

According to researchers, women with the BRCA1 or BRCA2 mutation have
a 20 percent chance of developing breast cancer by age 40, a 55
percent chance by age 60, and more than 80 percent by the time they
reach 80. The authors of this study say women who exercised during
their ****age years were more likely to develop cancer later in life
than women who did not exercise. The same was true for weight. If
women were average weight during their ****age years, they delayed the
onset of cancer.

More than 1,000 women with invasive breast cancer were enrolled in the
study. It is believed to be the first study to show exercise and
weight control can influence the onset of cancer in women who are
predisposed to cancer. Only about 100 of the 1,000 women had the
mutated BRCA1 and BRCA2 genes.

Interestingly, the authors point out some of those women had no family
history of breast or ovarian cancer because the genes were passed
through the father. Therefore, they stress that women should get to
know their family's medical history in great detail from both the
mother's and the father's side of the family.
