If you move at any time during the study, please contact the 3Gs study staff.

Testing of the collected samples will be done in a research lab and the tests are not for clinical use (meaning they are not intended to be used by doctors for diagnosing or treating medical problems). If your blood sample is one of those tested for environmental contaminants by the 3Gs study, you will have the option of choosing to have the results of these tests sent to you. At this time, only blood is being tested as part of the 3Gs study. Other specimens collected as part of the study will be stored for future use. These results are not designed for medical use and the information you receive may not suggest any actions you can take to reduce your health risk or exposure to these compounds. However, if you do choose to receive these results, we will provide you with as much information as we can, related to your results and will refer you to available resources to help you understand them.

Our studies may provide information that can be used to help prevent future breast cancer. Scientific findings from the study are based on data from combined results of individual samples. We will share study results with you through our website, newsletters, and publications in scientific journals. We are happy to provide you final study reports or reprints of any journal articles, when they are completed, at your request to the study director, Dr. Cohn. As the findings of the study are published, the CHDS and 3Gs websites will be updated to include summaries of these results.

You will be provided with results from the measurements of your blood pressure, height, weight, and waist size. The examiner will give you these results at the conclusion of the in-person visit. These results are for your information and are not to be used to assess your risk for disease. You may contact your health care provider with concerns.

If you are interested in more information about the history of the CHDS you can visit the CHDS website at: www.chdstudies.org. If you are looking for more information about breast cancer and breast cancer research, please see our list of resources here.

The staff of the 3Gs study will be happy to answer any and all of your questions about the study. You can find the 3Gs study staff contact information here.

There are a lot of ways to become more involved with women's health research and advocacy. We've provided a list of organizations that are involved in the fight against breast cancer—including awareness campaigns, influencing policy, engaging in human and environmental research and serving women who have been diagnosed with breast cancer. See our list here.

Yes! Women without children/only sons are just as important to our study as women who do have daughters. It is a generational study, but the information your family provided when you were young and your information as an adult will be immensely helpful to our studies on adult health. Your answers will also be representative of many other women your age across the US, and will provide valuable information about women's health
