Rochester, Minnesota - Jim Biles, M.D., understands cancer treatment. A urologist who specializes in cancer surgery, he has spent his career focused on helping people receive the cancer care they need. So at age 72, when Dr. Biles received his own diagnosis of an aggressive type of cancer, he knew how critical it would be to get treatment from someone with experience and expertise.

"When I found out I had a bone tumor, I started hunting around to see who could do the surgery. It turned out that there are very few people in the world I would trust with it," he says. "Not many do it, and even fewer have the experience that Dr. Sim does. He is the kingpin."

Dr. Sim is Franklin Sim, M.D., an orthopedic surgeon at Mayo Clinic's Rochester, Minnesota, campus. After a consultation with Dr. Sim, Jim decided to go through with a complex surgery at Mayo to treat his cancer.

"Being a doctor, I was pretty picky about all the details being well managed," he says. "It was exceptional. I really couldn't have had a better experience."
