What’s the study about?
The purpose of this study is to investigate whether cadmium, a heavy metal found in the environment, is related to breast density. The researchers will analyze urine samples from participants and measure the amount of cadmium, as well as other heavy metals. The researchers will also review recent mammography reports from participants to collect data on breast density.
Participating women also have the option to provide a saliva sample. The saliva samples will be stored for future DNA studies (for example, to better understand how genetics is related to breast density and measured levels of cadmium).
If you sign up for the Environmental Exposures and Breast Density study, the research team will contact you by Email to confirm that you are eligible for the study. If you decide to participate in the study, you will be asked to do the following:
• Sign and initial the consent form.
• Obtain a copy of the mammography report, also called a radiology report, from your most recent mammogram.
• Complete a health and lifestyle survey.
• Provide a urine sample; the research team will mail the urine collection kit to you.
• Provide a saliva sample; the research team will mail the saliva collection kit to you (optional).
• Return all of the items to the research team by mail, at no cost to you.
THIS STUDY IS OPEN TO WOMEN WHO RECENTLY HAD A MAMMOGRAM. WE ARE NOT ADVISING WOMEN TO HAVE A MAMMOGRAM ONLY SO THAT THEY CAN TAKE PART IN THIS STUDY.
