Dr. Guerra is a general internist trained in epidemiology and a health equity researcher. She is also the Vice Chair of Diversity and Inclusion for the Department of Medicine, and the Associate Director of Diversity and Outreach for the Abramson Cancer Center (ACC) where she also leads Community Outreach and Engagement. Dr. Guerra and her team have led dissemination and implementation research of breast and colorectal cancer screening interventions that include the development of patient navigation programs and “pop up” and mobile cancer screening events, which have engaged thousands of underserved, minority residents of Philadelphia and the surrounding region in cancer screenings. These efforts contributed to the increase in colorectal cancer screening and screening mammography rates in Philadelphia. At the national level, Dr. Guerra serves as the American Cancer Society (ACS) committees including National Advisory Council on Health Equity and Clinical Guideline Development Group. She has authored numerous articles including the current American Cancer Society’s colorectal cancer screening guidelines, which reduced the starting age for screening to 45, the cervical cancer screening guidelines which allow for screening with HPV testing alone (without a Pap smear) and the current HPV vaccination guidelines. These publications widely influence current clinical practice.
