Treatment Philosophy

I would like to give you a little background about myself, my training and my approach to treating cancer patients.

I did my undergraduate work at the University of Pennsylvania, majoring in bioengineering. I attended medical school at Temple University and did my residency in radiation oncology at the Fox Chase Cancer Center where I served as chief resident in 2005-06. During my training, I participated in many clinical research projects which have been published in various peer reviewed journals and presented at our national meeting of radiation oncologists. My research endeavors earned me the RSNA Roentgen Resident/Fellow Research Award in 2006.

Upon finishing my residency, I entered private practice, joining a radiation oncology group in Richmond, VA where I spent two years. During that time, I attended training in Pittsburgh, PA, becoming certified on the gamma knife, a radiosurgery treatment unit to treat benign and malignant tumors and other conditions in the brain. While practicing in Richmond, I worked in conjunction with a large neurosurgery group and treated many types of central nervous system tumors. I became board-certified in radiation oncology in 2008. I am now returning to Fox Chase as the Director of the Fox Chase Cancer Center- Buckingham radiation facility in Bucks County... Expand

Patient Stories

Edward Enoch

Prostate Cancer

Edward Enoch

Prostate Cancer

My name is Edward Enoch, and I am from Lansdale, Pennsylvania. I was sixty years old and two years retired when my life took a startling turn.

Like millions of other retirees, my wife Janice and I were updating our health insurance. We met with an agent who asked that I schedule a routine checkup. I thought nothing of it at the time—after all, I had no complaints about my health. However, once I received the results of my blood test, the confidence I had regarding my health started to waver.

Breast Cancer

I remember the day I was diagnosed so clearly. December 16, 2009. 

Scott Parker

Head & Neck Cancer

Scott Parker

Head & Neck Cancer

When Scott Parker was 45, he began losing his voice. He was soon diagnosed with laryngeal cancer by an ear, nose, and throat specialist. Then he sought treatment at Fox Chase Cancer Center because he knew of the Center's name and reputation. Scott had a long road ahead; he underwent radiation and had a laryngectomy, followed by reconstructive surgery, which was a success. He worked with Fox Chase's speech pathology department after surgery, which he now only needs on an as-needed basis. "I now come to Fox Chase for any medical needs I might have that they offer," Scott said. "If they offer it at Fox Chase, this is where I come. I’m so confident in the people here."

Prostate Cancer

John Mullarkey, Jr.

Prostate Cancer

I have always been proactive about my health and started having annual prostate exams when I turned 50 in 2007. My first report was great and showed that my PSA level was undetectable.

Kermit Moyer

Prostate Cancer

Kermit Moyer

Prostate Cancer

Raising hogs, cattle, turkey and chickens on 187 acres in rural Telford doesn't give Kermit Moyer much free time. But in 2009, when a bout of pneumonia at age 58 forced the lifelong farmer to take a break and visit his family doctor, even he was surprised to hear it had been 18 years since his last check up. "He wasn't happy with me,” said Kermit. Although he had no symptoms, and thought nothing of working 12-hour days, his PSA (prostate specific antigen) numbers were off the chart. PSA levels indicate a man's likelihood of developing prostate cancer.


Research Profile

Research Interests

I am interested in the effects of respiration on tumor motion in the lung, breast, and abdomen and in utilizing image-guidance to improve the accuracy and efficacy of radiation to these areas. I have also studied parameters for treatment decisions for salvage radiation after prostatectomy for recurrent prostate cancer and the risk of lymphedema in breast cancer patients treated with radiation after lumpectomy.
