Heather Spencer Feigelson, PhD, MPH

Senior Investigator

Heather Spencer FeigelsonHeather Spencer Feigelson, PhD, MPH, is a cancer epidemiologist with expertise in genetic susceptibility and genomics. Much of her research has focused the etiology of breast cancer. Dr. Feigelson participated in one of the first genome wide association studies of breast cancer, and currently is examining molecular markers in DCIS that predict subsequent invasive breast cancers. She has a long-standing interest in steroid hormone metabolism, has explored the role of obesity in cancer, including the impact of bariatric surgery, and the role of the gut microbiome on endogenous hormone levels and breast cancer risk.

Dr. Feigelson is the Colorado Regional Lead for the Kaiser Permanente Research Bank (KPRB) and the Scientific Lead of the KPRB Cancer Cohort. The KPRB is a national research project to build a biobank including data from 500,000 Kaiser Permanente members. Dr. Feigelson is committed to understanding factors that improve survival in those living with cancer; this work includes examining factors associated with second breast cancers such as mammographic density, BMI, and treatment patterns. She holds adjunct faculty appointments at the University of Colorado, Colorado School of Public Health, and Colorado State University.


Selected Research

  • Kaiser Permanente National Research Bank

    The KP National Research Bank is a collaboration across all Kaiser regions nationally funded by Kaiser Foundation Health Plan. The goal of the KP National Research Bank is to collect blood samples from 500,000 adult KP members and utilize them, combined with survey data and medical information to create a state of the art resource for genetic and health services research.
