About Cara E. Hahs, MD

I have dedicated my practice solely to the diagnosis and treatment of benign and malignant disorders of the breast since I finished my training in 2003. As a woman, I love being able to help other women, and am constantly inspired by their strength and dedication as they go through a difficult time. I strive to provide detailed explanations of problems and choices and to answer all questions. I think that it is important for a person to be involved in her own treatment decisions.
