A Tiny Particle That’s Gigantic in the Fight Against Cancer.

Seattle Cancer Care Alliance Proton Therapy is a cancer treatment center that uses highly targeted proton radiation to treat cancer. By precisely focusing on the tumor, proton therapy minimizes radiation to surrounding healthy tissue, reducing the risk of short- and long-term side effects.

SCCA Proton Therapy unites top cancer physicians from UW Medicine and Seattle Children’s. Located on UW Medicine's Northwest Hospital & Medical Center campus, we are the only proton therapy center in a seven-state region.

We’re committed to helping our patients live healthy, fulfilling lives by providing the best treatment and care possible. Our Care Team focuses not only on treatment, but also on patients’ overall well-being.

Managing life while undergoing treatment is a lot for anyone to handle. That’s why our Patient Services Team helps take care of the day-to-day needs for you and your family. We have extensive knowledge of local restaurants, recreational activities and spiritual places to help make Seattle feel like home. Our team also hosts activities for patients and their families where you can share stories and offer each other support. If you’re traveling from out of town, our team will help you find lodging and transportation during treatment.

Our Intake Team will coordinate medical record exchanges and collect information needed to evaluate your individual treatment needs. Your Care Team nurse will set up consultations, appointments and follow-up care. And our experienced financial counselors provide personalized help in understanding insurance coverage and payment.
