Breast cancer second opinion: checklist and how to ask

A second opinion is a normal request, and most teams expect it. Say: "I'd like a second opinion to feel confident in the plan. Can you help me arrange it?" and bring your reports. It can help you feel sure about the plan, or give you new options to discuss.
