Read our Breast Cancer research guide →UMBRELLA is a large, long-term study designed to follow breast cancer patients who receive radiation therapy at Utrecht Medical Center. The study collects information about how patients recover, how well their treatment works, any side effects they experience, and how their quality of life changes over time. By gathering this information from thousands of patients, researchers hope to better understand what works best and identify ways to improve care.
Breast cancer treatment has improved significantly, and more patients are surviving longer. However, doctors need to better understand the long-term side effects of treatment and quality of life for survivors. This study also creates a foundation for testing new treatment approaches efficiently, so promising new therapies can be evaluated quickly and fairly before being offered to all patients.

As a participant, you would allow the research team to collect your routine clinical information as part of your regular breast cancer care at the hospital. You would also be asked to complete questionnaires about your health, side effects, and quality of life at different time points. The study follows patients for the long term, meaning you may be contacted periodically over months or years to share updates about your recovery and wellbeing.
