Breast cancer (BC) remains the most prevalent malignancy among women. Prolonged exposure to chemical pollutants has been identified as one of its potential risk factors. Despite increased access to health information, important informational gaps persist regarding chemical exposure. This concern is particularly pronounced among female BC survivors due to their greater vulnerability. This study investigated unmet information needs related to chemical exposure among female BC survivors from Granada (Spain). The data were collected through 150 semi-structured interviews and focus groups between March 2023 and April 2024 and analyzed using the Framework Method. Most participants demonstrated limited awareness regarding BC and its potential association with chemical exposure. Nevertheless, 78.67% of them expressed concerns regarding the issue after diagnosis and anxiety surrounding the lack of reliable information from trusted sources on recurrence prevention. These findings highlight the need for public health communication that informs and empowers protective behavior.
