I did not have an increase in the CA 27.29… I had a decrease and I thought maybe it could’ve been from the weight loss. He was delighted to hear that I had lost weight but was noncommittal on the weight-loss affecting the reading. I had an excellent appointment with him. He explained a lot of stuff about the surgery and what I need and what I don’t need. He is not affiliated with my surgeons In anyway and wants me to give him complete reports of everything as it happens. I really like this man. He loves what he does. Thank you for asking
