PORTLAND, Ore. (February 26, 2025) ~ Cancer patients in the Portland area can expect expanded access to radiation treatment in the coming years, as a 4,300-square-foot addition gets underway at the Interstate Radiation Oncology Clinic. Leaders from Kaiser Permanente Northwest and its Radiation Oncology team gathered Wednesday to mark the start of construction on the project, which is designed to increase capacity as demand for cancer care continues to rise across the region.
The expansion is designed to help address a growing need for radiation therapy services in the Pacific Northwest, where more people are living longer after a cancer diagnosis. By expanding treatment and planning capacity, the project aims to reduce delays in care, keep patients close to home, and strengthen access to timely cancer treatment for the broader community.
"This groundbreaking marks a significant milestone for our team and our patients," said Dr. Tasha McDonald, Chief of Radiation Oncology at Kaiser Permanente Northwest. "We've been waiting a long time to build this expansion, and it reflects something very positive. Our ability to prolong lives with cancer treatments means we are caring for more cancer patients than ever before. Radiation oncology is a dynamic, technology-driven field, and our ongoing investments in state-of-the-art equipment enhance the safe and effective care already delivered to our patients. With the addition of this new facility and advanced machines, we'll be able to strengthen our ability to provide world-class, leading-edge treatment while addressing the increasing demand for cancer care throughout the Northwest region. This expansion both signifies our commitment to advancing medical technology and underscores our dedication to patient-centered care."
Construction is expected to be completed in 2027, with the expanded clinic supporting both cancer treatment and regional imaging needs. Once open, the facility will help strengthen cancer care capacity in the Portland area and support Kaiser Permanente's broader commitment to improving public health through early, effective, and accessible cancer treatment.
