I had a lumpectomy in 2005 for breast cancer followed by Chemo and radiation. In 2009 I started having things show up on my otherside and I decided enough already, take them off...and I've ever looked back. I decided on a bilateral mastectomy with immediate reconstruction. What they do is coordinate the surgeons and when the breast surgeon is finished the PS does the tissue expanders. My PS said that because I had radiation almost five years before he was confident that the skin would tolerate the tissue expanders. It's a LONG process but so worth it. I had the bilateral mastectomy/reconstruction in march of 2010, followed by the removal of the tissue expanders and replacement with implants in December 2010, then in march of 2011 nipple reconstruction (my surgeon didn't believe in nipple sparing surgery) followed by nipple tattooing in November 2011, so as you can see it is a very long process. You will get to know your PS very well...as you should. Always get a second opinion, not all PS think the same or have been trained in all procedures....that might be why he discouraged it in the first place but you won't know unless you get a second opinion.
