Treatment Philosophy

I am a medical oncologist who since 1991 has been devoted to only seeing patients with a diagnosis of lung cancer or mesothelioma. I am involved with a wide range of studies in lung cancer. Some of these involve new drugs. I work within an experienced multi-specialty team of surgeons, radiation oncologists, and pulmonists. All of these have a devotion and interest in the diagnosis, treatment and care of the patient with a chest malignancy. I joined Fox Chase Cancer Center in 1999.

    Dr. Treat & Staff are fantastic. I no longer get treatments, and are on a 12 week recall, which means to me I am in my happy place - Thanks to Fox Chase and Dr. Treat and the Nurses and all of the other staff there.
