Radiation Oncology Center

Winthrop Radiology Associates Oncology Building Mineola NY

The Division of Radiation Oncology is housed in the lower level of the Winthrop Main campus. The new outpatient center currently located at 264 Old Country Road, Mineola adds a third linear accelerator to the division.


About Us

The Division of Radiation Oncology treats over 700 new patients yearly with over 14,000 patient visits yearly. Our physicians participate in numerous multidisciplinary conferences to afford our patients access to individualized care with input from specialists in many oncologic subspecialties. Our physicians lecture frequently throughout the year and present research at major national oncologic meetings and journals.

Cyberknife Stergotactic Radiosurgery

This is a revolutionary treatment, which uses high-tech, cruise-missile-guidance technology and computer-controlled robotics to deliver precisely targeted radiation to tumors that were once considered inoperable.



Intensity Modulated Radiation Therapy (IMRT) is a newer way to deliver radiation. For selected patients, we offer this modality for cancer treatment. IMRT has the advantage of being able to treat tumors that received prior radiation or to treat tumors near critical structures. Our department has been using IMRT for over several and our data was presented at the largest national oncology meeting in the US (ASCO)


Prostate Brachytherapy

Our Prostate Brachytherapy (also known as "Prostate seeds) program is one of the most active in the area with approximately 200 seed cases done yearly. This procedure is usually done on an outpatient basis in conjunction with our excellent urology physicians with the majority of our patients going home the same day. Our physicians may recommend a short course of external beam therapy or hormonal therapy prior to see placement depending on the individual case.


Gynecologic Oncology

Over the past 3 years our gynecologic oncology program has grown to one of the largest on Long Island thanks to our close association with the Long Island Gynecologic Oncologists, P.C. group. Through monthly multidisciplinary Gynecologic Oncology conferences we are able to individualize a patients care to assure the best possible outcome. Our patients also have access to cutting edge protocols through our affiliation in the GOG national research group.
