The Hawaiʻi & Pacific Islands Mammography Registry (HIPIMR) database maintains a computerized database of women undergoing breast imaging in the state of Hawaiʻi, currently containing over 45 million images. Included are demographic, clinical and risk factor information, breast imaging interpretations, cancer outcomes, and vital status obtained through linkage with the Hawaiʻi Tumor Registry (HTR) and Hawaii State Department of Health and Vital Records (HSDHVR).
The main goals of the registry are to
- Identify next-generation breast imaging characteristics and their association with breast cancer in women of various ages and ethnicities.
- Examine clinical risk factors in women undergoing breast cancer screening in disadvantaged and underrepresented communities in Hawaiʻi and the Pacific Islands.
- Improve the accuracy and accessibility of breast cancer screening through quality control, alternative technology, and artificial intelligence.
We hope to learn more about how mammograms and advanced breast imaging tests can best detect breast cancer and what characteristics of women and tumors influence detection. Building this understanding can make screening more efficient and improve the outcomes for women with breast cancer.

Data collection is ongoing and began in 2019 with from the University of Hawaiʻi Cancer Center and from the National Cancer Institute. Data will include retrospective breast imaging and associated information going back to the initiation of digital mammography (approximately 2009) and prospective data through 2025.
All screening mammography centers identified in Hawaiʻi are invited to participate. Over twenty mammography facilities in Hawaiʻi are being asked to contribute data to the HIPIMR.
