Study Summary
This research study is being conducted to find out whether changes in household and personal behavior aimed at reducing exposure to environmental chemicals in dust (increased house dust removal efforts/cleaning and hand washing) and consumer products (increased us of personal care and beauty products that are free of chemicals including phthalates, parabens, and phenols) results in lower exposure to environmental chemicals including polycyclic aromatic hydrocarbons (PAHs) and endocrine disrupting chemicals including phthalates, parabens and phenols. These chemicals may have harmful health effects, as they can interfere with normal functions of the body. This study will also assess changes in breast tissue composition to understand the role of environmental exposures in breast cancer risk.
Primary Outcome
Breast tissue composition will be assessed at each clinic visit using an Optical Breast Spectroscopy machine, a minimally invasive procedure that is investigational and not currently FDA-approved. This machine places a light source on 4 different locations of the breast (at 12, 3, 6, and 9 o'clock) and reads the reflected light through the breast tissue. The OS exam will be completed twice on each side of the chest so that 8 measures are taken from the left breast and 8 measures will be taken fr
