About Dr. Konefal

I am currently the Medical Director of Lake Norman Radiation Oncology Center, and enjoy living in the community where I work. While I treat all cancers, I have a particular interest and expertise in treating prostate cancer with brachytherapy – the placement of radioactive seeds within the prostate. When I’m not in the office, I spend time with my wife and three daughters, and enjoy golfing, skiing, reading and traveling.

"I was impressed with the rapidly evolving technology and potential of radiation in curing, extending the lives, and improving the quality of life of cancer patients."
