Philosophy of care

I believe that decisions to pursue treatment are best made as a partnership between the patient and their doctor. That's why it's critical to ensure that patients receive thoughtful evaluations by several cancer experts, and are extraordinarily well-informed about the risks, benefits and alternatives to proposed treatments.
