THRIVE Well Cancer FDTN/Exercise_Creatine Supplementation

Summary

The study's purpose is to evaluate whether creatine supplementation can help breast cancer survivors respond quicker to exercise by improving strength, endurance, and body composition. We are seeking to compare information collected from healthy woman of the same age who have never had breast cancer to those participants who have had breast cancer and undergone chemotherapy treatment.
