Treatment Philosophy

A cancer diagnosis can be an overwhelming and life-altering event. I am honored to have the privilege of guiding patients and their families through each step of their care. The rapid pace of oncology research has led to the introduction of many novel and targeted therapies, and I take a collaborative approach to personalizing these treatment options for my patients. I am excited to join a comprehensive and multidisciplinary team at Fox Chase that can support patients and families through their treatment and recovery.

Michael Ples

  • Lymphoma

My cancer journey started one day in the summer of 2022 when I discovered what felt like a pimple on the back of my neck. The next day, the “pimple” had vanished, but two weeks later it was back, and this time it didn’t go away. Over just a few days, it grew so rapidly that I finally went to a local hospital to get it checked out.

After two months of testing, the doctors still couldn’t give me a definitive answer. Meanwhile, the welt on my neck had grown to the point where I couldn’t even turn my head to the right. That’s when I decided to go to Fox Chase Cancer Center.
