The Mayo Mammography Health Study is a large research study
conducted by Mayo doctors that hopes to find a way to identify
women at high risk for breast cancer, even before a physical
exam or mammogram detects the tumor. Researchers will study the
mammogram image and markers in the blood to find clues that may
lead to new screening tests. Researchers will also study the
association between lifestyle exposures, such as hormone
replacement therapy, and breast cancer risk. Specifically, they
will look at changes in the breast image and whether current or
past hormone use effects variations in breast tissue. In this
research study, we will collect questionnaires, mammograms and
blood samples from 25,000 women. To date, over 12,000 women have
participated. In creating this large resource, researchers hope
to find answers that will assist in future prevention and
treatment of breast cancer.
