Clinical Trial Protocol Description:

The purpose of this study is to determine whether the burden of environmental exposures is associated with risk for breast cancer. The microbiome is a measure of all the bacteria, both good and bad, in or on your body. The residential microbiome and the gut microbiome may be valuable markers of total ambient environmental exposures. The study will assess whether these microbiomes are associated with breast cancer.

The study is looking for both newly-diagnosed breast cancer patients and healthy volunteers. Participants will be asked to complete a lifestyle and residential history questionnaire and collect a stool sample and a dust sample in their home.

Participants will be given a $45 gift card once samples are collected and the questionnaire is completed.

Clinical Trial Eligibility Criteria:

In order to participate you must meet the following criteria:

  • Are a female, 18 years of age or older.
  • Are a resident of Cook County, Illinois.
  • Have the ability to respond to the questionnaire in English.
  • Have no history of cancer.
  • Have been newly diagnosed with breast cancer or DCIS (ductal carcinoma in situ).

You will be excluded from the study if any of the following criteria apply to you:

  • Have recurrent breast cancer
  • Have had any treatment for their cancer (for example: surgery, chemo, etc.).
  • Are currently on or have recently been on an antibiotic.

This is a partial list of inclusion and exclusion criteria.
