Study links physical activity and reduced risk of breast cancer
Oct 27, 2011
A new European study, which was presented at the 10th annual American Association for Cancer Research International Conference, found a link between physical activity and a reduced chance of developing a specific type of breast cancer - estrogen-receptor and progesterone-receptor tumor types.
The researchers also found that these risks were reduced even further when menopausal women regularly exercised.
"I would say that this adds to the evidence of what we have already seen in other research - that physical activity may reduce the risk of breast cancer," said Dr. Karen T. Liby, a research assistant professor of medicine at Dartmouth Medical School who was not involved in the study. "But it seems to be effective only in receptor-positive cancers."
According to the American Cancer Society, this disease is the second leading cause of cancer-related death among women behind lung cancer. However, the death rate has been decreasing since 1990 due to advancements in research and breakthrough breast cancer news. There are currently 2.5 million breast cancer survivors in the U.S.
