• I was recently diagnosed with Breast cancer [redacted]. After my lumpectomy with MGB in Boston, I chose to go with MGB in Danvers for my radiation. I was so happy after my first appointments with Dr. Derek Chism and RN [redacted], these two were part of the medical staff who would care for my needs. They are both so caring, professional, great listeners, making me feel most comfortable and explaining everything to me in a way I could understand and giving me the time to ask any questions. I would highly recommend Dr Chism and Nurse [redacted] to anyone in need of care who are empathetic and knowledgeable.
