Megan  Daly

Clinical Interests

Dr. Daly has a clinical focus on the treatment of thoracic malignancies, lymphoma, and head and neck cancers. She specializes in a variety of radiotherapy techniques including stereotactic body radiotherapy (SBRT), intensity modulated radiation therapy (IMRT), and image guided radiation therapy (IGRT).

Research Interests

Dr. Daly?s research interests focus on the use of stereotactic body radiotherapy for the treatment of early-stage lung cancer, metastatic lesions to the lung, and for primary and metastatic tumors of the spine. She also has a research interest in head and neck cancer, specifically in the use of advances in image guidance and conformal treatments to allow dose escalation while sparing normal tissues and reducing the side-effect profile of radiation treatment.

Philosophy of Care

I believe in treating cancer aggressively while maintaining my patients? quality of life and well-being. I feel that cancer treatment is a partnership between each patient and the team of specialists providing care. My goal is for my patients to fully understand all treatment options and to feel completely comfortable with their treatment decisions.
