As a board-certified radiation oncologist in Chula Vista's Eastlake district, Gina J. Mansy, MD practices through UC San Diego Health's Radiation Oncology South Bay program on Lane Avenue. Her tumor-site expertise spans breast, gynecologic, gastrointestinal, and skin cancers — the latter often referred from dermatology practices including West Dermatology Chula Vista after biopsy confirms malignancy requiring adjuvant radiation. She earned her medical degree from the University of Iowa Carver College of Medicine in 1993, completed an internal medicine internship at Brigham and Women's Hospital, and finished a radiation oncology residency at Tufts Medical Center in 1998. Her treatment protocols require concurrent supportive medications dispensed through pharmacies including Chula Vista Pharmacy for the antiemetic, analgesic, and radioprotective prescriptions that accompany fractionated radiation courses. An associate professor in UC San Diego's Department of Radiation Medicine and Applied Sciences, she has published peer-reviewed research on automated breast treatment planning software and image-guided radiation therapy quality assurance. Advanced modalities include intensity-modulated radiation therapy, stereotactic body radiation therapy, image-guided radiation therapy, and high-dose-rate brachytherapy delivered through linear accelerator systems calibrated for sub-millimeter targeting precision.
