I first met Dr. Sun in March to discuss the need for a mastectomy based on test results and the need for surgery based on my prior history w/breast cancer. She took the time to run a US in the exam room and then show me just where the ALH was situated and why the surgery was necessary. On my post-op visit on June 5, Dr. Sun gve me a copy of the complete pathology report and explained the terms ws not familiar with. I am so glad Dr. Sun was part of my tem.
