I had requested the one week option and my RO said she would do that, but wanted me to know research shows more impact on scarring and aesthetics, that it changes the appearance of the breast more. I personally have no idea! Glad the other poster had a great outcome. This was a tough decision for me. I start the 20th and ordered Mepitel, the film that prevents burns. My RO said it is great, but patient has to order it.
