- Female breast cancer patients between the ages of 18 and 70 years of age with a diagnosis of ductal carcinoma in situ (DCIS) or Stage I, II, or IIIA breast cancer and who are not currently receiving (and do not plan to receive during the duration of the study) chemotherapy or radiation therapy. The participant may be taking longer term therapies such as aromatase inhibitors, estrogen receptor modulators, etc. The upper age limit of 70 years was chosen to reduce the likelihood of adverse events or study drop-out due to increasing comorbidities (e.g., cardiovascular disease) that occur with age.
