Mammogram timing. One pre-diagnostic (baseline) and five post-diagnostic (T1-T5) mammograms of the contralateral breast were evaluated among 40 ER-positive breast cancer patients who were treated with tamoxifen. Mammograms were approximately one year apart, with the exception of the first post-diagnostic mammogram (T1) which was approximately 12 months after the initiation of tamoxifen and 18 months after the baseline mammogram.
