If you go to Mayo Rochester, ask to see Dr. Eugene Kwon if you are eligible. He oversees a very large clinic for men with recurrent prostate cancer, and he also has terrific providers from many other specialties to whom he can refer patients if needed. My husband has been Stage 4 with recurring metastases since he began seeing Dr. Kwon in 2011. Dr. Kwon and his team and other Mayo providers have kept him alive with a good quality of life ever since.
