SISTER STUDY RESEARCH

20th Anniversary Biospecimen Collection

As we commemorate the 20th anniversary of our work together, we are now inviting women in the Sister Study to provide another set of biological samples including blood, urine, and stool. With these new samples, we can better understand how changes in exposures and biological processes over time affect disease risk, quality of life, and survival after a breast cancer diagnosis. It is important we have women from all walks of life participating in this special effort. We hope you will participate in the 20th Anniversary Biospecimen Collection!

With the incredible help of our more than 50,000 participants, the Sister Study at 20 years has learned many important things about what affects breast cancer and other important women's health conditions. Even after 20 years of research, there is much more we can learn!
