New Hospital Construction Updates

UCI Radiation Oncology is proud to be an integral part of the new 800,000 square foot UCI health sciences campus currently under construction in Irvine. This new Department of Radiation Oncology will serve as a complement to our existing clinical footprint at the Chao Family Comprehensive Cancer Center in Orange and will allow us to expand our services to the greater whole of Orange County. Featuring 3 brand new state-of-the-art linear accelerators and a cutting-edge brachytherapy suite, the new Department is expected to begin treating patients in 2023. A full array of innovative treatments and clinical trials will be offered, consistent with our mission of improving cancer care and pushing the limits of what can be achieved for our patients!
