Who Can Join the Sister Study?
Until March 31, 2009 when study enrollment ends, you can join the Sister Study if —
- Your sister, related to you by blood, had breast cancer.
- You are between the ages of 35 and 74.
- You have never had breast cancer yourself.
- You are a woman living in the U.S. or Puerto Rico
PLEASE NOTE: In order to ensure that the Sister Study represents all women, at this time we are only enrolling women from specific groups that are underrepresented in the study to date.
Specifically, we still need women from the following groups to enroll in the Sister Study:
- African Americans, Latinas, Asians and Pacific Islanders, and Native Americans between ages 35-74.
- Caucasian women between the ages of 55-74 or with less than a bachelor degree.
While it is difficult to turn anyone away, Caucasian women ages 35-54 with a bachelor degree or higher will no longer be able to enroll, but can help the Sister Study in other ways. This group is now very well represented among our current participants.
Remember, enrollment ends March 31, 2009 so please act now. If you need help determining whether you can join at this time, please call our toll free number 1-877-4SISTER.
