Christin Knowlton, MD, is a therapeutic radiologist and is medical director of the Smilow Cancer Care Center in Hamden. Dr. Knowlton specializes in radiation therapy for breast cancer, lung cancer, bone metastases, and thymoma.

Dr. Knowlton says she was drawn to her field because it provides the opportunity to treat cancer “often with tangible results.”

“Radiation therapy is very successful at killing cancer cells and also helping with symptoms such as pain or bleeding from tumors,” she says. “In addition, some courses of radiation therapy span several days to weeks, which allows the physician the opportunity to really get to know the patients and their families.”

In fact, Dr. Knowlton says the best part of her job is meeting patients and answering questions about their disease process and treatment options.

“I also enjoy working closely with the members of the department of radiation oncology, including nursing, physics, dosimetry (treatment planning), and therapy to provide high-quality, patient-centered care,” she adds. “We work as a team to provide the best possible care for each patient.”
