A STUDY OF FACTORS ASSOCIATED WITH BI-RADS OUTCOMES ON BREAST IMAGING IN A COMMUNITY PARTICIPATING IN FREE SCREENING AT VINMEC CAN THO
Main Article Content
Abstract
Objective: To evaluate the outcomes of breast imaging screening and identify factors associated with breast imaging diagnoses in a community-based cohort. Subjects and Methods: This cross-sectional retrospective study included 1,482 women aged 21-80 years who participated in a free breast cancer screening program at Vinmec International General Hospital in Can Tho from May 1 to December 1, 2025. Results: The majority of participants were aged ≥40 years (78.9%), married, and parous. Breast imaging results were predominantly benign (BI-RADS categories 1-3, >95%), with a 3.85% rate of suspicious findings (BI-RADS 4). Only one case (0.07%) was histopathologically confirmed as breast cancer. Older age, menopausal status, and nulliparity were significantly associated with a higher likelihood of suspicious imaging findings. Conclusion: This study identified three factors significantly associated with suspicious or malignant BI-RADS outcomes (categories 4-6) in a screening population: older age, menopause, and nulliparity.
