Hi Barry,
I haven't got any answers for you as I've never had a flap, but it sounds like the flap is required for QOL issues. If they are planning further radiation then the flap issues would need to be resolved beforehand because tissues post radiation are much slower to heal.
I was wondering how you were doing and am sorry to hear that you now may have to face further surgery. Angelia and I are both starting our treatments on Monday. Please keep us posted with your progress and never forget that we will...KILL THIS CANCER!!
Sue
