I agree with the above posts regarding Dr. Charles Mangham. He is excellent, with experience. He's one of those Doctor's that has seen it all and has probably done it all. I had a ton of questions for him and he always answered my questions. I know that Dr. Mangham went the extra mile for my husband. Years later i still remain thankful that Dr. Mangham was a part of our lives when we needed him most.
Additional Doctors to consider
Dr. Sandra Vermeulen. Dr Vermeulen would be the Doctor to see for the radiation option. Dr. Vermeulen is currently co director of the CK clinic in Seattle, but she is extremely knowledgable in all areas of radiation treatment. In fact she's a board member of IRSA. A google search should provide a phone number. If i needed radiation treatment for any medical reason, she'd be the one I'd see first.
Other Doctors in the Seattle area
Dr Douglas Backous of Virginia Mason
Dr James Rasis Dr Rasis, was nearing retirement, or at least talking about it, He was located in the Heath Building next to Swedish.
Sorry I'm not as familiar with the Doctor's at the U of W and have been out of the loop for the past couple of years
Best to you
