Exercise Study for Breast Cancer Survivors

This study evaluates the link between muscle health and immune health in breast cancer survivors. Regular exercise is known to improve overall survival in cancer patients but the mechanism is not known. In this study the investigators will evaluate if improving muscle mass and strength via exercise improves the immune system's ability to fight cancer. This is a one armed study where in 30 breast cancer survivors will be recruited to a 4 month exercise intervention. Increase in muscle mass and strength will be correlated with immune cell frequency and function.
