The KTB is pleased to introduce you to Dr. Lexie White, NIH Stadtman Investigator, who requested and worked with data from KTB participants as well as from a previously studied cohort.
I found out about KTB at a scientific research meeting, where a colleague was presenting on work they had done in the study. I was excited about the unique opportunity to explore how normal breast tissue characteristics may be influenced by environmental exposures, such as air pollution, in order to help us better understand how the environment influences breast cancer risk.
I have used existing breast tissue histologic measures that are available in the Komen Tissue bank population.
We took the residential address that the study participants lived at when they donated their tissue sample and estimated their annual average exposure to air pollutants. We found that participants who lived in areas of higher air pollution exposure tended to have higher terminal duct lobular units counts (TDLUs), which are associated with a higher risk of breast cancer.
The KTB samples have allowed us to explore how air pollution may impact the normal breast tissue in ways that may predispose women to go on to develop breast cancer later in life. This work has provided support for a causal relationship between air pollution and breast cancer.
I don’t think that this work will impact treatment options but may be used by clinicians to encourage awareness of air pollutant exposure and how it may be related to breast cancer risk.
