Summary
This research will examine the effectiveness of vitamin D or placebo (the placebo is a tablet that looks like Vitamin D study drug, but has no Vitamin D study drug in it), with and without physical activity (walking and progressive resistance exercise), in treating bone loss in women who have undergone treatment for breast cancer. The investigators would also like to find out if the physical activity program improves cardiovascular fitness, energy expenditure, muscular strength, muscle mass, and balance. One hundred five (105) subjects are expected to take part in this study. The investigators don't know if bone loss in breast cancer survivors should be treated differently than bone loss in other women.
Measure the Amount of Bone Mineral Density Loss in Non-metastatic Breast Cancer Patients Receiving a High Dose Vitamin D Therapy Along With a Structured Home-based Walking and Progressive Resistance Exercise Program.
