Who is Gary Onik?

Gary Onik is the inventor of ultrasound guided cryosurgery for both the prostate and the liver.

Onik treated the first liver patients with cryosurgery in 1986 and the first patient with ultrasound guided prostate cryosurgery in 1990, and has developed techniques and instrumentation that have been integral to the minimally invasive treatment of cancer.

Onik pioneered the concept of a Male Lumpectomy in which only the cancerous area of the prostate is destroyed by freezing; his research in this area was honored by the Society of Uroradiology as the most important research paper at their 2004 annual meeting in Scottsdale, Arizona. He also utilizes a new biopsy technique called 3D Prostate Mapping Biopsy, in which the extent and location of a patient's cancer is determined by a more accurate biopsy carried out with specialized guidance devices.

Onik is the former director of Florida Hospital/Celebration Health's prostate cancer research program. He received his B.A. degree from Harvard College and his MD degree from New York Medical College. He completed a radiology residency at the University of California at San Francisco and a fellowship in Ultrasound and Interventional Radiology Research at New England Deaconess Hospital, Harvard Medical School. He is the two time president of the American College of Cryosurgery and has authored several books and many articles on the subject of oncology.
