M:(6 - 1)Let me switch gears now and turn into the subject of the connection between rigorous exercise and preventing breast cancer. A study showed that there was a drop between 26 and 40 percent even if you take the lower end of that spectrum. That is significant.
W: It’s a very large decrease. So,(7- 1)one of the first studies with the Nurse’s Health Study followed 3 ,000 people for 14 years and they saw between a 26 to 40 percent decrease in death and recurrence in individuals who already had breast cancer.(6 - 2/7 - 2)This newest study, the California Teacher Study, followed 110,000 women from the earlier mid-90s up until 2002 and they saw that the women that were exercising the most had the greatest reduction in breast cancer, as you said, about 31 percent, about 5 hours a week.
M: What about the impact of exercise on the breast cancers?
W:(8)We’ve always thought that it was through some kind of hormone, because when you exercise, you have lower levels of it. So we thought that was a reason that you got the disease.
M: So to wrap things up, for a woman who gets a diagnosis of breast cancer is difficult, does it make sound that the first thing you would tell that woman to do is go out and start exercising?
W: Well,(9)see your doctor and get a very good medical team and then make sure that exercise is an adjunct to that, and the research that we are doing at the Friedman School is showing that we can get a lot of people exercising, so it’s really important for your brain as well as reducing your risk of breast cancer.(10)And as a woman with a history of Alzheimer in my family, I am certainly going to keep exercising.
M: A lot of people are going to pay attention to it. Professor Miriam Nelson, thanks! Good to have you here.
W: Thank you very much.
