"I was diagnosed with breast cancer that had traveled to my lymph node in December 2021. Dr Sigalove's approach was absolutely professional. She explained the diagnosis by listening to my concerns and questions in a very thorough patient and caring manner, while outlining her best recommended approach for treatment. Dr. Sigalove completed my surgery to remove the cancerous tumor in February 2022. The surgical procedure went without a hitch and left little scarring. I was absolutely pleased with the care I received from Dr. Sigalove. I highly recommend her in the unfortunate event you are ever diagnosed with cancer. Happy to inform, I am in remission and my mammograms have been clean. I feel my best decision in finding a qualified surgeon for treatment was when I found Dr. Sigalove. P.S. Staff and timeliness for appointments were also above reproach! Was never in waiting room for more than five minutes!" C. Nelson
