What is the best course of action for breast cancer treatment?

The visit to the Oncologist comes AFTER the Surgery. That is when they will take the next step. Yes, it is a warranted course of treatment, and next will either come radiation or chemo, or both. Your mom's health is more important than losing a breast. If she is not satisfied with her general surgeon, she should get a second opinion. I saw two of them before I chose mine.
