general_content

Dr. Lyons was drawn to breast surgical oncology in part because of the opportunity to support patients early in their diagnosis and guide them through treatment decisions. He works closely with patients to help them understand their diagnosis and navigate surgical options as part of a broader, team-based approach to breast cancer care.

He performs breast cancer procedures including breast-conserving surgery, skin-sparing and nipple-sparing mastectomy, and flat aesthetic closure. He also has a particular interest in the de-escalation of axillary surgery, with the goal of reducing treatment burden while maintaining effective cancer care.
