For this study, researchers assigned 101 women with breast cancer to a 16-week program of cardiovascular exercise and strength training or to "normal" care. All women had their insulin and blood glucose levels measured, as well as their weight, body composition, and waist and hip circumference. Participants had already completed chemotherapy and/or radiation but had not started on any hormonal therapies, said study author Dr. Jennifer Ligibel, an instructor of medicine at Dana-Farber and Harvard.
Women in the exercise group lowered their insulin levels by about 20 percent, Ligibel said, an amount that approached statistical significance. These women also had a trend toward improved insulin sensitivity, meaning how their body responds to the hormone insulin.

"The ultimate goal is to look at exercise vs. not exercising and see what happens to women's breast cancer," Ligibel said.
