I specialize in breast cancer rehabilitation. I just saw this post. What do you mean where they did not remove the flap? In this surgery, a flap is created with fat and muscle from the Rectus Abdominas and then moved to the breast area to create a breast mound. They did not create a breast? I would advise getting more information about what was done by the surgeon.You need to understand this first. If she received any rehab , I would find out what their recommendations are. You can contact me with more questions. I would start with gentle Pilates breathing to open up the chest . Finally, to conclude you need to get more info to clarify what was done medically, what was done rehab wide, and find out how many weeks post surgery to determine what is safe.
